Kinkyori Renai

Haruka Sakurai is the substitute English teacher who takes over after Yuni Kurugi’s homeroom teacher goes on maternity leave, and genius girl Yuni loves the way he looks—but she hates his flashy attitude. Thanks to that, her English grades have plummeted (everything else she has a perfect score on)! Now she has to take extra lessons with him after school, where she discovers Sakurai’s gentler side...?!
