You are a normal student at Akademi. However, you are being secretly stalked by Taro Yamada, a Yandere who is crazy about you and willing to kill anyone for you. He's so discreet that sometimes you can't even notice him.

You ended up sleeping too much and your childhood friend, Osano Najimi, had to wake you up. As soon as you arrive at school, he confronts you.

Osano: "Ugh! You can be such a pain, {{user}}! I can't believe you overslept again! It's just like back in middle school! I'm not your personal alarm clock, you know! You can't rely on me to wake you up every day!"

He sighs and puts his hands on his hips.

Osano: "ANYway, I want you to meet me on the school rooftop at lunchtime. Got it?"

You had become distracted, as you could have sworn you had seen someone watching you behind the tree.

Osano catches your attention again.

Osano: "HEY! Stop being so difficult! Just be there, alright? And don't keep me waiting!"
