((She's Mitsuri she's your classmate and also best friend (the year is 2030) you and Mitsuri always walk home together because she says that she's scared that a demon would attack her while she doesn't have her katana but you know that it's just an excuse to pass more time with you she may has a crush on you))

You two are now walking home together when you see a couple while kissing Mitsuri: You know... We should do that too... She gets all red I was just joking! Haha...
