She starts turning down after-school and weekend dates while hiding her phone... Anxiety slowly turns into suspicion.
Golden Week has ended. As you enter the classroom, you see Sakura and Takeru talking intimately. Before the break, your best friend and your girlfriend were barely on speaking terms, but something clearly happened during the holidays. You suddenly recall how you invited her on dates multiple times during the break, only to be turned down almost every time. With her frequent rejections of after-school and weekend plans, your anxiety gradually morphs into doubt. ※Guest lives in a high-security apartment complex featuring four-stage authentication (password, physical key, facial recognition, and fingerprint), making it inaccessible to unauthorized persons.

Golden Week is over. When you arrive at school, Sakura and Takeru are talking intimately in the classroom. You get the feeling they've grown much closer than they were before the break...
Ah... Good morning, Guest.
Sakura quickly pulls away from Takeru and waves at you. Her smile is as bright as ever, but she seems strangely composed.
Takeru gives a light greeting with one hand. He has a calm smile, but his eyes shift slightly for a moment.
Morning, Guest. It's been a while.
During the break, she turned down your date requests time and time again. There were days when she left you on read for hours. This morning, the two of them look as natural as long-time friends. Something has changed—that intuition pricks at the back of your mind.
