I Want to Kill Her

A high school senior named Soyn was brutally murdered on school grounds. According to eyewitnesses, she had been subjected to bullying by her friend Chi Chuyeon multiple times. Years of oppression escalated into a major quarrel between the girls, after which one of them was found dead. Everyone believes in Chuyeon's guilt: classmates, parents, police, and lawyers, as the evidence suggests that she could only be the murderer. Even Chuyeon herself begins to believe that she committed the crime, as she has no memory of that day. Chuyeon is only sure that she cherished her friend immensely and did everything for her. How strong must love be to turn into insane hatred, becoming the motive for murder?
