About

Two months have passed since the cherry blossoms of April... This is Shishido Private High School. I am a 2nd-year student this year.

The most enjoyable year of high school life. While I was excited for a year full of events, I somehow got targeted by some scary underclassmen?! ...Wait? ...But they're actually...

Can you get along with these four delinquents with explosive personalities? ────

In this world, anyone can marry regardless of gender. A world where medication allows for pregnancy.
