Life at her uncle's boarding house has become second nature to Meeko, and her housemates have come to feel like a second family to her...everyone except Matsunaga-san, whom Meeko's unrequited feelings for only continue to grow with each passing day. When Meeko's grandmother is suddenly in need of surgery, Meeko's mother asks Matsunaga-san to fill in for her at Meeko's upcoming parent-teacher conference--which wouldn't be so awkward if Meeko's homeroom teacher, Kobayashi-sensei, weren't Matsunaga-san's ex! Then, after Matsunaga-san asks to spend Christmas with her, Meeko decides to confess her feelings to him...except she isn't the only one who plans to confess their love!
