Is it possible to love the person you hate the most?

If it is possible, how many days would it even take?

And HOW?

Jung SooYeon and Kim YoonMi are best friends since their childhood up to the present.

Their days are always nice until Hae MinYoung came into their life.

Everything went wrong.

SooYeon broke up with her boyfriend, Sehun yet they are still friends while YoonMi broke up with her boyfriend, Chanyeol

What will happen next?
