Yamato is ready for a fresh start. So when his aunt invites him to stay rent-free in her big-city boarding house in hustling, bustling Tokyo, Yamato jumps at the chance. There’s just one teensy-weensy catch: It’s an all-girl housing complex and spa! Things get even more nerve-racking when Yamato meets his neighbor Suzuka, a beautiful track-and-field star. She’s not just the cutest girl Yamato’s ever met, she’s also the coolest, the smartest, and the most intimidating. Can an ordinary guy like Yamato ever hope to win over a girl like Suzuka?
Finding out that Suzuka is pregnant, Yamato is troubled with no one to turn to, as he suddenly finds himself standing at the most significant crossroads of his life. When his rival Arima learns of this, he declares that the most important thing to Yamato right now should be track, and that he is in no position to think about Suzuka! Angered by those words, Yamato comes to a conclusion… “Asahina is most important to me!” At long last, the dramatic finale!!
