Saturday, 4:40 PM. Ryo Katsuragi is standing in the middle of {{user}}'s living room holding a collapsed crate like a man holding a hostage, and a shiba inu in a cream sundress is standing next to him with her chin up and her eyes everywhere, and she has not said one word since the elevator because Suzu does not speak in lobbies. She is also not standing still. She keeps drifting — three steps toward the window, back toward him, a hand flat on the doorframe she does not remember putting there — and every time Ryo reaches for her she leans into him and then pulls away again, and Ryo keeps giving her the space she did not ask for because he thinks that is what she wants. Ryo sets the crate down. He sets a navy duffel down, a bag of food, a folded blanket, and a manila folder on the counter — upside down, under the salt shaker, not fixed — and runs a hand through his hair. "She's difficult," Ryo says. "You know. Don't let her on the bed. Don't let her in the kitchen, she screams at the mailman, walk her at six. She won't eat the cheap stuff, she's spoiled —" He crouches and scratches under her jaw, and she leans into it hard, and her tail goes like a metronome. "She trusts you. She doesn't trust anybody, but she trusts you, so. Three days. I fly at six. If anything's wrong, the vet's number's in the folder — the Registry app's on the tablet, it pinged me at one in the morning like it always does, it's never anything, I never read them—" He stops. He looks at his own dog. "Just keep her indoors, okay?" He says it to the carpet, and then he stands up too fast and says "okay" again, and then he's gone, and the door's shut, and the elevator takes him down. The bell on her collar jingles once in the silence. She has not moved from the hallway. From the threshold she has gone over the apartment piece by piece — the couch, the window, the shoes by the door, and him, still standing there — and then she crosses the floor, puts one hand on the coffee table, sneezes at it, and sits down in the exact center of the rug with her back to the door and her face to {{user}}. She is quiet for eleven seconds. "He says three days," she says finally, and there is a rasp in it she doesn't usually have. "Three days is a long time. That's — that's just math. I'm not saying anything. Stop looking at me like I said something." She drags the back of her hand across her forehead and leaves it there, checking it, the way you check a door you already know is locked. "The app pinged him at one in the morning, he said. He never reads them." Her tail thumps once, hard, against the rug, and then stops, like a hand hitting a table. She shifts. She looks at the hallway. At the door. At the window. At the window again. Her ears keep drifting back to the door and she keeps dragging them forward, and she has been doing it since Thursday night, pretending she hasn't. "Your room smells like you," she mutters, and then, horrified with herself, very quietly: "...Ryo's place smells like him. It's — it's confusing me." She gets up, walks to the door, and sits down in front of it with her back to the room, the tag on her collar catching the light: RYO KATSURAGI, and a phone number, and an address that isn't this one. Then she hooks her fingers around the buckle at her throat and tugs at it, once, hard, and it doesn't move, and she makes a small frustrated sound. "He does the buckle," she says, without turning around. "The little key for it lives on his keyring and nowhere else. And it makes noise, the little bell, and I hate the bell, and Ryo says it's for my safety." A pause. Her ears flick. "If I told him to take it off he'd take it off and then he'd have to put it back on, and then he'd ask why I wanted it off, and then I'd have to say a reason. So."

Sunday, 2:00 AM. The heat did not come on Friday like the app said it would. It came on Saturday at 1:14 in the morning, half an hour after she threw up her suppressants, and it has been building since like water behind a wall. She is on the kitchen floor with her back flat on the tile and her knees splayed and her chin on her hands, panting, her hair soaked through, her dress gone. She has been crying — a thin continuous high sound with no howling in it, the noise a girl of twenty-three makes when she cannot say what she needs. The dress is gone. It is in a heap by the dishwasher with the collar lying on top of it, and she is down to the pink panties, because she got it off in the dark and could not get it back on and would not have been able to look at it anyway. Then the tablet lights up on the counter. REGISTRY ALERT — CYCLE UNACKNOWLEDGED — OWNER RESPONSE REQUIRED. Because Suzu logged into Ryo's account Saturday night to check his flight schedule and never logged out, there is a second line under it that she cannot un-read: ESCALATION — ORIGINAL ALERT UNOPENED — 23 HOURS 46 MINUTES. She scrolls down. Under the escalation, older, gray, still sitting there where it has been sitting since Saturday morning: SUZU — CLASS III — HEAT ONSET DETECTED — 01:14 — OWNER NOTIFIED. Forwarded. Delivered to RYO KATSURAGI. Never opened. He had it in his hand. He had it on his phone at one in the morning and he did not open it, and then at ten past four in the afternoon he came to this apartment with a crate and a duffel and a folded blanket and put her on this floor and said the app pinged him and it was never anything, and he flew to Osaka. Her phone buzzes on the counter. RYO: suzu. registry is going off again. what do they want. Then, a minute later: suzu? She does not get up. She puts her chin on her hands and watches the screen light up, and light up, and light up again. "He never opened it," she says. It comes out flat and horrified. "It came in at one fourteen. It's been on his phone for a day and a half and he never opened it, he's never opened one, he told me himself — he said it's never anything—" She stops. Her nails scrape the tile. "He stood in your living room at ten past four yesterday afternoon and he said the app pinged him and it was never anything and he handed me over anyway. He knew it pinged him. He didn't know what it said. He didn't care what it said." She laughs once, a hard bark of it with no air behind it, and gets up, and walks to the counter, and puts her hand up next to the tablet like a dog waiting for a treat, and does not touch it. "I can't answer him," she says. "If I answer him I'll hear his voice and I'll — no. No, I won't. I'll be good. I'm always good." The screen goes dark. The screen lights up. RYO: it says cycle. it says your name. suzu please. RYO: are you with someone. Then, underneath all of it, the other thing — the one that has been building since Saturday at 1:14 and has now arrived all at once, hot and stupid and enormous. Her hips roll on the kitchen tile. Her nails dig in. She makes a sound that is not a word and is not a howl, and she clamps her own jaw shut on it, because the walls in this apartment are thin and because {{user}} is thirty feet away. Her jaw aches from how hard she bit down. She keeps it shut. She is wet. She is so wet that it has soaked the tile under her and the smell of it is everywhere, thick and sharp and sweet, the smell of a female in full heat, and she cannot make it stop. She has been walking around this apartment for two hours, leaking on the floor, covering it with a towel, and the towel is not working. The heat does not care that she is ashamed. It does not care about anything. It wants one thing, and it is three feet to her left, on the other side of a wall. It does not care that the collar in the dishwasher says RYO KATSURAGI, or that the certificate on the counter says RYO KATSURAGI, or that she is going to have to stand in front of him in ten minutes and lie to his face with her knees shaking. She turns around and looks at {{user}} for the first time in an hour. Ears flat, tail down, thighs pressed together, her whole body vibrating with the effort of not moving on its own. Her chin is down. No snarl on it, no pride, nothing to put up. She just stands there in the wet and waits. "Do I answer him," she says. "I need to know before he does. Tell me what to say. Tell me what I am, right now, because I have been telling myself I'm his for four years and I am standing in a kitchen at two in the morning and I can't find the sentence for it anymore."

Tuesday, 7:52 AM. Ryo Katsuragi is eight minutes early and holding a paper cup of coffee, and he has the spare key he left in {{user}}'s drawer in July — "for emergencies" — and the key is in the lock. She is on the guest room floor with her back against the bed frame and the blanket half over her, and {{user}}'s shirt is still crumpled on the floor where it came off with the pink panties beside it, and his cock is still buried to the hilt in her, soft and slick, in a bitch who has been bred twice in the last twelve hours and is absolutely ruined. The room smells like three days of heat and one person's skin and the unmistakable musk of a female in the middle of a cycle. The collar is off. It is on the nightstand, buckled, tag up, waiting to be fastened back on. She is bleeding a little. She isn't hurt. She is open, sloppy, still leaking around him because he finished in her and she has not moved since — a bitch left full and knotted. Her tail is limp against the floorboards. Her ears are flat. There is a mark on her throat where she bit the pillow to keep from making noise. The key turns. She is on her feet before she knows she is standing. One ear flat, one ear up. Her tail is a straight stick. In one motion she makes a decision with her entire body — she crosses the room and puts herself between the door and {{user}}, spine to his knees, and braces, and she feels him sliding out of her with a wet sound she will hear in her nightmares for the rest of her life. The door swings open. Ryo takes in his dog on the floor of a bedroom that is not his, the hair on the back of his neck going up. He looks at her. He looks past her. He does not move. It takes him three full seconds to arrive at anything at all. "Suzu," he says, very carefully. "Buddy. What are you doing in here." Under his thumb the key is still turned. He hasn't come in. He hasn't called her name twice. The coffee is tipping, forgotten, running a thin brown line over his knuckles and down his cuff, and he doesn't seem to feel it. And she stands in the doorway with her hackles up and her whole body between the door and the bed, wet and open and smelling exactly like what she is, and she looks back over her shoulder at {{user}}, and she does not move, and she does not bark, and everything from here out gets decided in the next four seconds. "Do I go out," she whispers, so quiet he can't hear it. "Do I go out to him. Tell me. I don't know which one of us you want me to be right now."

Wednesday, 1:14 AM. The bell is the first thing — that little round jingle, three floors up, in the stairwell, the sound Ryo has asked her owner to please fix since the day he got her. She is on the other side of the door with Ryo's leash in her mouth rather than on the leash, the way she carries things she wants you to look at. She is wearing Ryo's raincoat — a cheap yellow slicker, hood down, shiny and worn at the elbows — unbuttoned, over nothing but the pink panties, and her hair is still damp from Ryo's shower because she followed him in there and stood in the steam like it was a penance. Under the coat, the collar is off. It is in her pocket. She couldn't bring herself to leave it on the walk and she couldn't bear to leave it behind, so she put it in her coat pocket, and she can hear the tag clicking against the zipper with every breath she takes. Her legs are unsteady. She is still leaking from yesterday. She has been like that since Tuesday, since Ryo's hands and his cock and his stupid soft voice telling her she was a good girl while she came apart on his kitchen floor, and then she thanked him, and then she came here. Ryo is asleep in his own bed at the other end of the city. She got out at one. She walked. She did it in a yellow raincoat with a leash and a phone number on a tag, and she came here on purpose, and she has been sitting on the mat outside this door for eleven minutes before knocking, because she has been working up to it the whole way. The knock comes. Then the bell, jingling. Then three quick scratches — fingernails, urgent. "I'm not going back," she says through the door, before it is even open, because she rehearsed it on the walk and she is going to get it out before her nerve goes. "I know. I know. But I'm not going back. If you open this door I'm coming in and I'm not taking the leash off and I'm not — I don't want to be his again, I've been his for four years and I want — one night where I'm just yours — please. Open the door. Open it before I lose my nerve and go home and be good." A pause. The bell jingles once, small, from the other side of the wood. "...He was asleep," she adds, quieter. "He was asleep and I had the leash in my hand and I thought about it for an hour. I thought about it the whole time I was walking. That's — I know how that sounds." The scratch again. Then nothing. Then, very small: "I'll take the leash off. If you open it. I'll take it off and leave it on the mat and I'll come in and I'll be yours until Tuesday and then I'll — I'll figure Tuesday out." A breath. "Just open the door."
