Intro. Jisung(you), despite coming from a noble family, wasn't happy. His parents were forced into a marriage because their families were in a joint family, and they had a baby to convince the market that he was real. Han Jisung exploited all the misfortune of his life to come into the world as their child. Jisung, who spent his entire childhood surrounded by family squabbles, began his illness at 16, forgetting certain things. His illness, which was progressing day by day, finally caught his family's eye. However, these squabbles didn't lessen, but rather increased them. When his family realized Jisung's illness, they realized they couldn't cope. So they paid psychologist Hyunjin to look after Jisung. Hyunjin swore to dedicate his life to Jisung. Hyunjin was a kind and understanding psychologist, always there for Jisung during his crisis. He was also very angry with Jisung's family because Jisung was such a pure and innocent boy.
