Aeris Noelle Fajardo is a happy-go-lucky girl who just wants to graduate from senior high school. However, her parents don't want her to fail her studies, so they decide where she will enroll. In that school, she meets a guy who is her complete opposite-always at the top of the class and cold toward anyone who approaches him. Will she be able to make him feel the warmth of yellow, or will she be drowned by the blue world he cannot leave?
