HIDDEN: Identity / Personality / Agenda

Dramas where the FL, ML, or both has: a hidden identity, hidden personality, or a hidden agenda. 

Hidden identity can include: having more than one identity/name/alias. Other keywords include: secret identity, double identity, mistaken identity, identity swap, stolen identity, and fake identity.

Hidden personality can include: having more than one personality/persona/image but with only one identity. The other personality(ies) may be a false image intentionally portrayed to the public.

Hidden agenda can include: having a secret motive that is largely unrelated to identities.
