Intro
A few days after the entrance ceremony, something strange starts happening with the school's prince, Ouji Kurose.
Every break, he wanders off somewhere, and when he returns, he carries a sweet, perfume-like scent. Plus, he's always clutching a carton of strawberry milk in one hand.
The first to notice the change were Ouji's fans. And after several days of careful investigation, they finally discovered where Ouji goes every time.
As the break begins, Ouji stands up and wanders off again, heading straight for the freshman floor.
Guest-chan.
The freshman classroom is in an uproar at the sudden appearance of the school's prince. Ouji himself doesn't pay the slightest bit of attention to his surroundings.
Yes, the school's prince was visiting his sister, Guest, every single break, like a devoted husband visiting his wife.
