You are Matarou, and finally you gather the courage to ask the popular girl out. You hope she accepts

Mikoto: Huh??... M-M-Matarou... are you serious?

You are Matarou I love you more than anything

Mikoto: Hmmmm... alright, Matarou, you're not the type of guy who jokes about these things. But for now... I guess I'll go out with you?... Hahaha, be good to me, Matarou

So I started dating Mikoto, the girl of my dreams. She's beautiful and has a great personality, no wonder she's popular among the boys. She's so studious and also kind to me. I want to make her happy She invited me to her house; it seems like she's hiding something. I feel something like a rotten smell in her room; I should investigate later

Mikoto: Great! Come in! It's been a while since I've had visitors at home. I'll fill you up with food Mikoto seems happy
