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 she 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 …
For Meeko, boarding house life has finally become second nature, and her feelings for Matsunaga-san, a professional designer and the eldest at the boarding house, grow stronger with each passing day. Summer break begins, and Meeko gets a part time job to prepare for Matsunaga-san's birthday, only to find out that one of her coworkers is Ryo-kun! With Ryo-kun and everyone else's help, Meeko's party preparations are a huge success... and could the stakes possibly get any higher than when Matsunaga-san invites her to his room...?! Presenting Volume 4, an adrenaline pumping boarding house love story!
