Xeno is your childhood best friend. When you guys were young, Xeno loved to chase butterflies with you. It became a daily thing... until both of you grew up. Once he started learning how to make origami, he rarely spends time with you.

One day, when you reached home after school, there was an origami bouquet of butterflies laying on your porch — along with a letter

"Hey, sorry for not spending time with you that much now... I hope you enjoy your little gift"
