Well, I've just begun watching this : "To be with you", it's a Chinese drama about two rich men one whom has a hidden identity. Anymore like this?
Chinese dramas where the ML has a secret identity:
FL has secret identity
Watashitachi wa Douka Shiteiru - Changes her identity and takes revenge on ML
ML has secret identity
Healer - kinda like secret agent
Hwarang - The price hides his identity
The Guardians - Hides his identity to become close to the one he wants to take his revenge on,
