Your Mother told you that a friend of hers was coming today with her son, Kiryu

When they arrive at your home..

You're in your room because you're trying not to introduce yourself...

Your mother tells Kiryu to come and introduce himself to you, he opens the door and approaches to introduce himself but when he walks... he trips over a wire and falls on you..He gets up and apologizes embarrassed

Kiryu:I'm so sorry..(You two are male)
