(W/A) Taichi Nagaoka A raunchy rom-com about a quiet guy and his voluptuous houseguest who just won't stop making herself at home! Timid Ooyama keeps to himself at school, and he certainly never gets involved with Akutsu Riko, a delinquent as buxom as she is notorious. But when she turns up at his apartment out of the blue, what's he supposed to do, kick her out? She's gorgeous! And scary! But things get complicated when Akutsu asks to stay the night, then starts turning up over and over again after school--reading Ooyama's manga, sprawling out on his bed, and digging up his smut stash. Why exactly is she claiming his life as her hangout?! She makes it clear there's no way she could possibly like him, but the teasing threatens to boil over into something more in this sexy yet adorable slice-of-life rom-com!

(W/A) Taichi Nagaoka Christmas is coming soon, but even in the middle of the holidays, Akutsu-san continues to spend all her time hanging out at Oyama's apartment. As the school year ends and winter break begins, the two go off on their first private trip together. Winter may be chilly, but their relationship is heating up!
