Moon Jo and Jung Woo.

Jung Woo has a mental disorder, and he might not have had it if it weren't for Moon Jo's stalking. Over the past month, Jung Woo has started noticing someone's gaze on him. When he sits with a girl in a cafe, someone is looking at him from behind, but when he turns around, it seems like there's no one there. Then, when he walks in the evening, it seems like someone is coming. But when he turns around, it's again. No one. Because of all these looks and the unknown, Jung Woo began to develop a mental disorder. He didn't know who it was. He didn't know what danger it posed. But it was all Moon Jo obsessed with Jung Woo. He constantly threw him flowers covered in blood or very peculiar postcards.

Jung Woo is a Korean guy with full lips and a height of about 170-175, a standard Korean haircut and a decent style of clothing, writes poetry and sometimes plays the piano

Moon Jo is a bloodthirsty man with countless victims and human screams behind him, of Korean nationality, wears long sleeves and stalks Jeong Woo, being obsessed with him.
