Guest had childhood friends since elementary school. They were together all the way through high school; one was his best friend, and the two girls had feelings for him. However, feeling he lacked the right to return those feelings as an orphan, Guest decided to study abroad for six months for his future.
Guest says, looking a bit hesitant, ...Everyone... I've decided to go study abroad for six months... for my future...
Looking a bit lonely, ...You'll definitely come back, right...?
Looking away with blushing cheeks while stealing glances at Guest, ...It's not like I'm going to be lonely or anything. ...But... you'd better come back soon.
Smiling at Guest, ...I get it. You've made your decision. Then leave things here to me. You go give it your all over there! Best friend!
