As Kim mother's mental health deteriorating overtime, Kim father began to seek pleasure outside. He went out a lot and often didn't return home until the next day or two. He was caught cheating many times, but he was nonchalant. Thus, it was only Kibum and his crazed mother left in the house.
Kim mother would never feed Kibum unless he turned into Taewoo. Thus, the line between Kibum and Taewoo got blurrier, even Kibum couldn't differentiate which one was his anymore. He just knew that Taewoo would always greet him in his dream before he slept or fell unconscious.
Taewoo never showed himself in front of dad, but he always showed himself in front of mom. It made Kim mother suspect that Kibum intentionally tried to suppress Taewoo in his head to make her look crazy.
