Kimi ga Kirai na Koi no Hanashi

Good-natured Chihiro Hiyoshi takes being the class rep seriously, but her partner, Haruka Kisaragi does not. He's got too many rumors swirling around him, but when a chance meeting brings them into each other's lives for just a moment, they form an unsteady bond. But bad boy Haruka may be too much for a good girl like Chihiro to handle...but something in her may have just awoken a hidden softness in him, too.
