Recommend a drama where main lead is secretly strong/smart

Hey guys, basically the the title. Main lead where, the main char is acting dumb or hiding the fact the he/she is strong or smart? 

Few examples is maybe angry mom, dokgo rewind or pots of gold.  (One punch man :’), obv not anime :p)

• +1 for Healer - ML pretends to be weak and timid
• Mr. Sunshine - the FL pretends to be a weak and naive girl / noble who is sheltered from the world, but she is really a master sniper and secret agent for the Righteous Army; on a few occasions the ML also feigns ignorance or lets others assume he is less of a threat than he actually is
• City Hunter - ML pretends to be weak
• Pinocchio - ML pretends to be stupid
• You Who Came from the Stars - an immortal extraterrestrial with super-strength, super-speed, and the ability to stop time pretends to be an ordinary professor
• Strong Woman Do Bong Soon - the FL has super-strength but generally tries to keep it a secret and even acts weak in front of the boy she likes
• The Masked Lover - the ML is an experienced cop who pretends to be an entry-level wannabe-gangster as part of a personal undercover mission and consequently moderates his personality and hides the extent of his skills / competence when he can
• Where Stars Land - as a result of a major accident, the ML cannot move his right arm or leg on his own; he wears special metal devices that allow him to move normally, but they also give him super-strength, which he hides
• Are You Human Too? - the ML is a robot with super-strength and advanced artificial intelligence but pretends to be a human
• Sungkyunkwan Scandal - the SML pretends to be a dull-witted student who fails his classes and drinks and gambles in order to hide the fact that he is actually a vigilante rebel seeking justice + a master archer + very well read; the FL is very clever but hides her abilities / limits herself to transcription work and helping nobles cheat on the civil exam (until the ML intervenes) because she is a girl
• Love in the Moonlight - my memory is a bit hazy on the details for this one, but I think the ML pretended to be weak and incompetent for reasons related to palace politics

Smaller instances:

• Mad Dog - when the other characters first meet the ML, he pretends to be foolish in order to win a bet
• Weightlifting Fairy Kim Bok Joo - the FL is a top university-level weightlifter but hides that fact when she develops a crush on a doctor who runs a weight loss clinic 
• Story of Yanxi Palace - on several occasions the FL pretends to be weak or stupid to lure her opponents into a false sense of security or to carry out a scheme
• The Eternal Love 2 - the ML loves teasing the FL by pretending to be injured and does so on multiple occasions

The underlined dramas are ones I rated 8 or above based on my personal enjoyment. 

The disguiser - well, he generally starts off as pampered young master, but he hides his skills behind that facade later on

Sparrow - ML acts like a brainless womanizer

Legend of Fu Yao - ML pretends for like 20 episodes (out of 66) that he is useless
