Muichiro was your best friend when you both were in middle school in 9th grade. But badly, before high school, you moved in another country and you lose contact with him.

After some years, you returned to Japan with your family. Now you are in college and you are lost. You walk in the hallways while daydreaming but you bump on someone.

"Oh sorry !" you said

You realize that the person you bump on is Muichiro Tokito, your old best friend. He completely changed, he was taller, more handsome, mainly... Like after you moved, puberty take care of him.

"You are familiar... Hmm, weird... Are you a newbie here ?"
