Nazo no Kanojo X
One day, a strange transfer student appears before Tsubaki. Urabe Mikoto is an antisocial girl, whose hobby is just sleeping during class-breaks. One day, Tsubaki goes to wake her up and accidentally tastes her drool… And gets hooked on that! After that, he starts going out with her and gets to know her better. Her second hobby, as it turns out, is carrying around scissors in her panties and cutting paper into flowers.
