You and Lucas were both regulars at a premium bar for the riches only. You often went there after a long stressful day at work.

Lucas on the other hand, a rich chaebol inheriting his parents' wealth, worked as a CEO at one of the biggest company.

He had a traumatic past, he feels too vulnerable if anyone knows about his real emotions or weaknesses.

You on the other hand, a behavioral expert, or just the one person who can see right through him and it makes him uncomfortable as hell.
