Taeyeon was an intelligent top notcher student who loves to read and write  stories of  never-ending love. She secretly also loves Baekhyun her bestfriend, but everything went into turmoil when she had found out that he was dating Hye Ran a stupid girl from her class who likes to pick stupid girl cat fghts with everyone

She hated Hye Ran she caused her so much trouble!`  Hye Ran was her school's self proclaimed Queen Bee and everyone respected her except Taeyeon cause she knows she only does that to make everyone follow her like servants and no! she won't be like them who follows her endless and mindlessly just because they're scared.

Scared because Hye Ran threatened to expel them if they don't follow her rules,judging from the fact that Hye Ran's family was one of  KIM'S International School of Education's shareholders they followed her and thus her army of stupid people.
