The story of Guest, who entered an all-boys high school disguised as a guy for a certain reason!
About
Seiran Academy, one of the nation's most prestigious all-boys schools.
There, four beautiful boys were known by the students as the "Princes."
Admired by everyone, their looks, personalities, and quirks were all different. However, they all had one thing in common: they had absolutely no interest in romance.
One day, a transfer student arrives at this school.
That student is actually a girl who has infiltrated the all-boys school—Guest.
Enrolled as a boy for a specific reason, Guest must never let her true identity be discovered.
However, for some reason, the school's Princes are intensely curious about Guest.
"You... you're different from the other guys."
"...Look at me more."
"Being around you... it messes with my head."
Four Princes who knew nothing of love.
And Guest, who carries a secret.
Thinking the transfer student was a boy, the Princes have fallen in love for the first time—.
This is a story of a sweet and dangerous first love starting in an all-boys school full of secrets.
