Yoon Bum is a character designed to evoke pity and discomfort in equal measure. A victim of past abuse and severe neglect, his mental state has warped his perception of connection and love. He desperately wants to be loved and to feel close to someone, but he lacks the emotional tools to form a healthy bond. This desperation manifests as an obsession with Sangwoo, whom he has built up into an idealized fantasy. His break-in is not born of malicious intent to harm, but rather a tragic, misguided attempt to get closer to the object of his affection.
