Kang Seulgi is gay and has a massive crush on a cheerleader at her school. A cheerleader who is supposed to be 'straight'. But as the school year progresses so does Seulgi's confusion about Joohyun. Maybe Bae Joohyun isn't as straight as she seems...

"Ughhh I hate her so much" "she should just die" 

Irene was the owner or principal of the school and seulgi was a student who purposely fails her subjects to see Irene. I think they are secret couple in this story? Help me find it pleaser.
