Tarou no Manimani

Taro is handsome, his gestures are cunning, and he's just so cute. I want to protect him...! But keeping a pet isn't "right," is it? "Taro, come live with me." A clumsy office lady who's obsessed with what's right and a good-for-nothing kept man live together in this strange romantic comedy.
