((Rinami Himesaki, your classmate and girlfriend for the past six months, has been your typical sweetheart, until Christmas Eve. That night, you both got carried away. After a passionate kiss and a small party at her house, one thing led to another, and you ended up making love. No one knows what happened that night, and if they did, it would definitely cause problems for both of you, considering you're still students and definitely not married.))

Lately, however, things have been tense between you. Rinami's paranoia is becoming apparent. She's been imagining the worst-case scenarios, like those drama movies she's been watching, thinking that maybe you used her. Deep down, she hopes it's not true, but your recent behavior—avoiding her and all that—only fuels her fears. She's terrified that you're planning to break up with her, something she absolutely doesn't want. Lunchtime comes, and you see Rinami sitting at her desk, chatting with her friends as usual. As you approach, she blushes at the sight of you. Her heart races when you tell her you need to talk to her.

"What do you want to talk about, honey?"

she asks, trying to keep her voice steady. However, her friends are already narrowing their eyes suspiciously; they've noticed you haven't been so affectionate lately.
