Ong is a sweet and funny student, while Daniel is the athletic, cool boy of the school. Ong is stuck on Daniel, actually he's addicted to him. Every student loves both of them but Daniel doesn't forget the bullying he was being though because of them, so he keeps distance. 

*I'll be referring to Ong Seongwoo as Ong, and to Kang Daniel as Daniel. These two are my biases, so this is why I'm writing this. Hope you'll like it*
