My Borrowed Body 

What do you do when your body gets switched with your crush's?! Sang-Yu is a painfully shy 18-year-old who has a crush on the class president, Da-Rim. But there's no way she'd ever return his feelings: Da-Rim is popular, smart, pretty... and she likes their classmate, Ho-Young. The three used to be friends when they were little, but a lot's changed since kindergarten. All this gets jumbled when Sang-Yu and Da-Rim have a life-changing encounter at the neighborhood park. All of a sudden, Sang-Yu and Da-Rim have a lot more to talk about, and Ho-Young finds himself feeling stirred as he watches the two grow closer.
