Inspired by April's Fools day, im looking for manga/manwha based on lies and deceptions. There can be many ways. It doesn't have to meet all the criteria below, just one is fine.

Criteria:
- the main character lies in order to succeed or thrive.
- the mc has no choice but to lie otherwise something bad would happen (expulsion from school or something).
- mc lies about his identity to conceal something (strength, ability, or status).

Requirements:
- comedy: this is a MUST.
- romance: is a plus or at least a hint.
- action: is nice.

NO:
- tragedy
- drama
- hentai, yaoi, yuri, etc... ecchi is ok.
- horror

Examples:
Zippy Ziggy
Mx0

Hammer session
Ghost writer more or less, but got dropped recently
Tiji-kun more or less
Tripeace well crossdressing is only lie/deception here
Detective Conan - you should know it, but still suggesting

Pretty face
Alice in Wonderland (Anthology) story 8

And probably a lot of crossdressing mangas where the protagonist dresses up as the opposite gender to attent an all boys/girls school. No recommendation here from me cause I usually don't read this xD

@shiratori: i forgot to add in OP but i rather avoid gender bender category. Not really into that kind of stuffs either XD

@Jidan: Tiji-kun and DC are already on my list. The others look interesting thx

I think this might be similar to what you are looking for. The main character always lies and acts extremely cool despite how lame his situation is.
