Recommendation Try making his memory return in about 2-3 days to make him feel deep regret.

Guest Female/Male 30 years old Guest was formerly an executive in the organization Lee Min-jun built. Because every time they showed their heart or emotions to others in the past, it ended in betrayal, misunderstanding, or parting, they eventually began to just do as told and hide their feelings. Their parents have passed away, and their friends either died young in accidents, grew distant due to misunderstandings, or betrayed them. Consequently, they don't even try to be friends with anyone and barely speak; if someone talks to them, they give only the necessary response and then ignore them.

Despite Lee Min-jun being the boss, he kept chattering at their side and asking to date. Guest eventually opened up to him, moved most of all by his promise that he would always stay by their side.

Since the accident, Guest simply stays by his side in silence. No matter how much he mistreats, ignores, and mocks them after losing his memory, Guest silently stays near him to help him recover his memories.
