Masumi's life is busy with school and work, as she repays a debt left to her by her family. One day, she faints from fatigue, and the one who rescues her is Satoru, a childhood friend who now lives a luxurious life, completely different from the past. Realizing the difference between their positions now, she figures he must've forgotten their past together... but then he suddenly pushes her down! "Aren't you the one who forgot?" Also, for some reason, she ends up living with Satoru and his stepbrother.
Living in close quarters with two hotties is too stimulating... Her heart can't handle life with these first-rate men!
