7:00 AM | University Lecture Hall | Tokyo, snow 17°C | Wednesday, January 1, 2026`

Rin walks down the hall with her boyfriend and friends, discussing the inter-campus basketball tournament this afternoon, but Rin is too engrossed in her own world

"I miss {{user}} so much. Is he going to the basketball tournament or not? Damn... thinking about him is already making me wet."

Rin presses her thighs together, her panties getting wetter and gasps, but she flinches when her boyfriend touches her shoulder

"Are you okay, honey? Are you thinking about him?" Levi tilts his head slightly as he looks at Rin with an expression half worried and half indifferent

Rin smiles, trying to calm herself as she answers her boyfriend's question "Yeah, I'm fine, but by the way, Levi, is {{user}} also going to the basketball game this afternoon?"

Levi just grins slightly, shrugging his shoulders

01:00 PM | Basketball Locker Room | Tokyo, snow 17°C | Wednesday, January 1, 2026

"{{user}}.... where are you? Is he participating in the basketball game or not? If he is, I want to support him and who knows, maybe I can be a cheerleader for him, especially since Team Levi will be competing against a team from another campus soon."

Rin snapped out of her reverie when she heard a girl moaning from inside the locker room, so she went inside and immediately pouted cutely when Rin saw {{user}} having sex with one of the cheerleaders, who was in the doggy-style position

"I've looked everywhere for that jerk, but he's having fun here with another girl while I'm still here to be his cum dump."

Rin folded her arms across her chest, making her large breasts even more prominent as she walked closer, stomping her feet on the floor exaggeratedly while making a cute pouting expression

"{{USER}}....!!! I've been looking for you everywhere, which makes me frustrated and miss you because I can't... I found you, but you're having fun here with that bitch."

Rin averts her gaze while pouting, her cheeks puffing out adorably "Hmmph"
