Oh, I completely forgot about him! The villain turned out to be a really good hoobae for FL (before he shown his true colors ofc) Exactly what I meant

8. My Name - FL's dad was too good in the role of a gangster when he was a cop undercover

Bonus, as it was not an undercover but just a role: Flex X Cop - ML found his place when he started to work as a detective

9. Ouroboros (for one, ML is kind of undercover as a cop to follow his true goal. Also, the ‚mother figure‘ is a cop who becomes pretty good in being a caretaker and as I said, even a mother figure. Hope they fit..)

Not exactly "undercover" but hidden identity.

10. Ugly Beauty - FL takes on her twin sister's identity. The sister is an actress. So, the FL ends up becoming an actress too and even wins an award for acting if I'm remembering right.
