[Congratulations on entering the prestigious Geumseong School.]

Mook In-ha, a rabbit beast-person, enters the prestigious Geumseong School in place of her older brother, In-ho, who eloped with his girlfriend.
It was natural for In-ha, an ambitious rabbit beast-person, to harbor dreams and hopes of proudly advancing into human society.
However, Geumseong School is an all-boys' boarding school, and In-ha is a girl.

‘It's okay, I just have to endure for 3 years!’

“What is this smell?”
“It smells like fruit. Did someone bring something to eat?!”

In-ha's secondary manifestation, which suddenly began one day.
Next to her, experiencing an uncontrollable surge of pheromones, is…

“Beom Seong-jun, please… help me…”
“Mook In-ho, you really… hid this?”
