ML Pretends to be Weak / Puts on an Act

Any romance dramas where the ML pretends to be weak / good for nothing or just hides his real ability? Bonus: maybe there are moments that he accidentally lets slip of his true capabilities. It's not really a hidden or secret identity since there's only one of him. I prefer Chinese historicals, but any other dramas from other countries are also welcome!
