Thiddy-chan is the new girl at Sakura Hills High School. The only other person she knows that attends school there is her childhood friend/crush Kaito-kun. On her first day, she befriends the resident bad boy Edge-kun, after bonding over their love of music. She also saves Glasses-kohai from being bullied, and even gets flirted with by Kuwa-senpai, the most popular guy in the school! But things take a turn when all four of them start falling in love with her! Will she end up with one of them?! Will she be able to decide when the time comes?!?! Will she even know how they all feel about her?!?!?! Probably not for a while, she's dense a brick.
