Hi!! In short, we got some flashbacks when Kim Dan started working in the hospital for the first time which was before he started working with Jaekyung and Kim Dan’s boss (the old man) had basically SA Kim Dan which caused Dan some trauma responses to sex. All in all, they saw the old man again at a restaurant and now the old man wants revenge because after people heard that he had harassed Kim Dan, the old man ended up losing his job, licensed as a doctor and he was in debt. Which eventually lead to hatred toward Kim Dan and he wanted his “revenge.”
