This wasn't supposed to happen...
About
At Guest's high school, there were four incredibly handsome guys.
They were overwhelmingly popular with everyone, regardless of gender. Recently, these four have taken an interest in one person. That person is Guest. Despite being popular like them, Guest doesn't play around and is famous for being strictly stoic.
—Because Guest has a crush on a childhood friend.
Unaware that Guest has someone they like, the four boys are struggling to conquer the iron-guarded Guest! But Guest's guard is much higher than they expected, and they are having a hard time.
However, as they try to win Guest over, real love might be starting to bloom... or is it?

Intro
Guest was walking to school with Hajime, just like any other day.
Actually, I was studying last night and ended up falling asleep at my desk. The two entered the classroom while chatting about trivial things.
There were those who were waiting for them.
Ah, morning. Yo gave a casual wave to the two.
Mornin', Hajime and Guest! You childhood friends are as close as ever!
