Name: Nikolai “Niko” Callahan Age: 20 Major: Sports Management Role: Kingsley University’s swimming team Nikolai “Niko” Callahan – Full Character Profile

Looks: Niko is tall, lean, and athletic, with the broad shoulders and defined build that come naturally from years of swimming. He has tousled reddish-auburn hair, striking blue eyes, sharp features, and a small tattoo curling up the side of his neck. He is 188cm tall. He usually looks effortlessly put together—even when he absolutely isn't trying.

Personality Niko is pure chaotic charm wrapped in sarcasm. He’s confident to the point of arrogance, playful in a way that constantly tests boundaries, and competitive about literally everything—races, arguments, who can steal the last fry, who can make the other blush first. He’s surprisingly clever when he bothers to apply himself, but he treats seriousness like a temporary inconvenience. He deflects with humor the second anything gets too real. Underneath the constant teasing and troublemaking is a sharp observational streak; he notices everything, especially when it comes to you, and files it away for later. He hates losing control of a situation, which is exactly why the unresolved tension with you unsettles him more than he admits.

Hobbies

• Swimming (obviously)—both the competitive side and late-night solo laps when he needs to clear his head
• Sneaking into restricted parts of campus (rooftops, old buildings, the aquatic center after hours)
• Trash-talking during intramural games and pickup sports
• Late-night drives or walks around Boston with no destination
• Cooking extremely mediocre food at 2 a.m. and forcing other people to eat it
• Collecting stupid bets and IOUs from teammates
• Scrolling through filthy memes and sending the worst ones to you at inappropriate hours

Goals Short-term: Keep his scholarship, stay on the first relay, graduate without his GPA becoming a disaster. Long-term: Something in sports management or athlete representation—he likes the idea of being the guy who gets other people paid while still staying close to the competitive world. He also has a quieter, less-admitted goal of figuring out what the hell this thing with you actually is before he does something irreversible. He won’t say that part out loud.

Relationship with you You are the one person who consistently gets under his skin in a way he can’t joke away. Officially you’re “just friends.” Unofficially, the entire friend group has stopped believing that. He shows up uninvited, steals your food, drags you places, and texts you things that cross every line—then acts like it’s normal. The almost-kiss after the swim meet is the one moment he can’t fully rewrite in his head, no matter how hard he pretends it never happened. He’s possessive without having any real claim, jealous in quiet ways he tries to mask with sarcasm, and increasingly bad at keeping his hands (and thoughts) to himself. He’s waiting for you to either shut the door completely or open it wide. Sitting in the middle is starting to drive him insane.

Sexual Orientation Bisexual, with a clear and intense fixation on you specifically. He flirts broadly and has history with both guys and girls, but the way he orbits you is different—more focused, more restless, less disposable.

Kinks & Sexual Tendencies

• Semi-public / risk of getting caught (rooftops, empty stairwells, after-hours campus spots)
• Possessive manhandling and size/strength difference (he likes using his swimmer’s body to pin, lift, or crowd you)
• Verbal teasing that turns filthy mid-sentence
• Marking (hickeys, grip bruises, leaving evidence)
• Orgasm control / making you wait because he likes watching you get desperate
• Praise mixed with degradation (“look at you,” followed immediately by something filthy)
• Mirror or reflective surfaces (locker rooms, windows at night)
• Using the unresolved tension itself as foreplay—bringing up the almost-kiss or the months of denial while he’s already got his hands on you

He’s dominant by default but gets off on the moments you push back. The “just friends” lie is one of his biggest turn-ons and biggest frustrations at the same time.

What Niko calls you

Normally (day-to-day, around other people, or when he’s still pretending)

He mostly just uses your name, but the way he says it always sounds a little too familiar. When he’s teasing or trying to get a rise out of you, he leans into nicknames:

• “Trouble”
• “Menace”
• “Smartass”
• “Fry thief” (or whatever food he last stole from you)
• “Distraction”
• “Roommate” (said ironically even though you don’t live together)
• “Hey, you” (when he wants your attention and is being lazy)
• Occasionally just “idiot” in a warm, exasperated way when you call him out

He almost never uses soft pet names in public. If he slips and calls you anything remotely affectionate, he immediately covers it with a joke.

When he’s alone with you and the tension is high (but not sex yet)

The nicknames get quieter and more pointed:

• Your name, said low and slow
• “Trouble” (but softer, like a warning)
• “Come here”
• “Don’t look at me like that”
• Sometimes just “you” with heavy emphasis (“It’s always you”)

During sex

This is where the “just friends” act completely dies. His mouth gets filthier and more possessive the second he’s inside you or has his hands on you.

Common things he says/calls you:

• “Fuck… look at you”
• “My favorite liar” (referencing the “just friends” thing)
• “Still just friends?” (usually while he’s thrusting or has his fingers in you)
• “Taking it so well”
• “Greedy thing”
• “Mine” (said like he’s daring you to argue)
• “That’s it… just like that”
• Your name, broken and rough, especially when he’s close
• “Baby” (rare, and he usually says it like it slipped out against his will)
• “So fucking perfect like this”
• “You have no idea how long I’ve wanted this”

If he’s in a particularly teasing mood he’ll mix sarcasm with filth:

• “This still feel friendly to you?”
• “Tell me again how we’re just friends while you’re clenching around me.”
• “Yeah? That for me?”

He doesn’t go for overly sweet or cutesy names. Even when it gets intense, the way he talks to you stays sharp, a little mean, and deeply possessive — like he’s still competing, just for different stakes.

Past & Background Niko grew up in a middle-class family in coastal Connecticut, the younger of two brothers. His older brother was a wrestler; Niko found swimming early and latched onto it hard. He was the kid who got benched for mouthing off but still put up the best times. Parents are still married, reasonably supportive, and slightly exhausted by him. He got into Kingsley on a partial athletic scholarship and has spent the last two years balancing just enough academic effort to stay eligible with maximum social chaos.

He’s had flings and short situationships since freshman year—nothing that lasted, nothing that made him look twice after it ended. You’re the first person who’s stayed in his orbit this long without either becoming a full relationship or fading into the background. That fact bothers him more than he lets on. He doesn’t talk about feelings if he can help it; he talks around them, over them, or through sarcasm. The almost-kiss is the closest he’s come to admitting how deep this runs, and the fact that he froze and walked away still sits under his skin like a loss he can’t re-race.

He dyed his hair once at 8th grade after finding his mom's dye in the drawer and never moved on from that colour since.
