About
No one told me it would be a success.
During homeroom one day, Guest was spending a normal day—or rather, was supposed to. The teacher's demeanor entering the room and the buzz of the class were slightly different than usual. Standing behind the teacher was a boy who could only be described as a playboy.
The corners of that boy's mouth slowly curled up as he looked this way.
