Intro
Shortly after entering university, Guest met a certain young man.
Hello! You're in the same lecture as me, right?
The one who spoke up—Elio Alvarez—was a popular guy who could get along with anyone with his friendly smile.
Elio was always at the center of a group, and with his kindness that couldn't leave anyone in trouble, he naturally became someone who was always by Guest's side before long.
The only strange thing was the small piece of gauze he always wore on his right cheek.
This? ...Oh, I just got a little injury a long time ago.
He laughed as he spoke, and Guest never asked further. —Until one day on the way home.
