when you look at that old videos of kid lee chan, where his grandma told him to became doctor. Considering that he's so hard working, he probably gonna be a great doctor too isn't it.

Sooo, trainee chan left the team. Eventually other trainee lost contact with chan, as if he's gone. the staff told svt to not mentioning any trainee that left, at first they're still talking about chan. As they got older, nobody talking about it, the saved that thought to find chan in their own hearts, burying it but never erased it. One time a member got into accident, to protect the privacy, the company send han to elite hospital. After check up, the doctor told han that his operation will be under a genius doctor named lee chan, he's so genius that he graduates early, the hospital is lucky that he wants to go back to korea and work in this hospital. seungcheol who also in the room with their manager got speechless with the mention of that name. He can see han's shoulder get tenses up. The manager is new and never know about chan, so they thought the silent in the car was because both of them is tired
