Hate Girl

Unrequited love is like breathing in fine dust: toxic, yet impossible to avoid. For over five years, Da-Hye Jung has harbored a relentless crush on her childhood best friend, Beom-Seok Lee. She vows to make one final, undeniable confession the moment her college entrance exams end. But her grand romantic dream is shattered when she catches him having a secret kiss… with her own older sister! Caught in a messy web of betrayal, petty resentment, and a chaotic four-way romance, Da-Hye’s lifelong crush is about to become a total disaster. After all, love hurts, but family hurts worse.
