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?
Suzuka can't wait to spend Christmas with her new boyfriend, Yamato. But then she's invited to an exclusive collegiate training camp over the holidays. She breaks the bad news to Yamato, hoping that he'll beg her not to go. Aiming to be a supportive boyfriend (and forgetting all about Christmas!), Yamato insists she attend the camp. Now Suzuka is furious, and clueless Yamato can't figure out what he's done wrong. Will Suzuka and Yamato be spending Christmas apart?
