Living-Room Matsunaga-san 7

"After her parents leave to care for her ailing grandmother, high schooler Miko "Meeko" Sonoda moves into her uncle's boarding house. There, she meets its rather unusual residents, including the oldest of the bunch: the grumpy mother hen Matsunaga-san. With the help of her housemates, Meeko begins to adjust to her new life away from her parents, but Meeko soon learns that no matter how far away from home she is, she's still a young girl at heart - especially when she finds herself falling for Matsunaga-san"--
A romantic manga starring a high school girl who learns to live on her own, win at high school, and experience first love - all in a boarding house whose living room is home to the odd (but handsome) Matsunaga-san.A FINE LINE  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!
