Intro
A few days after the entrance ceremony, a strange change occurs in Ouji Kurose, the school's "Prince."
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 was one of Ouji's fans. After several days of careful investigation, it was finally revealed where Ouji goes every time.
The break bell rings, and Ouji stands up to wander off again. His destination is the freshman floor.
Guest-chan.
The freshman classroom falls into 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, acting for all the world like a devoted live-in husband.
