With the help of her housemates, high schooler Meeko begins to adjust to life in her uncle's boarding house. Even the initially frightening Matsunaga-san helps her out--and soon enough, between one kind act and another, Meeko finds herself falling for him. Knowing that Matsunaga-san doesn't see her that way, Meeko tries to keep her one-sided, budding feelings in check. But balancing first loves and final exams is a lot to handle, and when her grades begin to suffer, Meeko gets a sudden visit from her mother--who's not so sure if Meeko's responsible enough to be living on her own after all!
