As you can imagine the person he killed her brother. He doesn't know it until very end. She forgive him and doesn't say him. When he learned the truth he really devastated wanted to kill himself but she says she forgive him etc. And a police investigation about his brother started again and they suspect male lead. But she kind of beg police neighbor to stop investigation since she forgive him . (Most of them is the things I understand from looking pictures it can be wrong so keep that in mind)
