Haru to Koi to Kimi no Koto

Mishima Hiroka is a girl who has a trauma in regards to anything related to love. Drawn by the rule that forbids dating within the dormitory, she enters that school thinking she'd be able to spend her high school days peacefully... only to discover it was a rule that was loosely imposed. And there she meets Sata Airi, a slightly eccentric but handsome boy.
