I can think of a few dramas where the ML has information that has to do with the FL, but she doesn't know anything about it. None of these dramas are exactly like Well-Intended Love, though. None of the secrets are as simple or as purely motivated by a desire to get the girl. But if what you're looking for is mystery, slowly revealed, I wholeheartedly recommend these dramas:
Love Like the Galaxy: Part 1 and Love Like the Galaxy: Part 2 - he's a master manipulator who at times comes off like the typical mighty general who's awkward in the social realm. As a character, he's truly likable. But there are layers.
Pinocchio - he has major secrets that are related to her and her family.
Tomorrow with You - through time travel, he sees a future for himself in which she's involved, and he doesn't like what he sees.
Should We Kiss First? - I know this one is a hard sell, because the characters are middle aged, but it's really good. Mysterious dimensions are revealed.
It's Okay, That's Love - ML has some mystery, and plot twists reveal deeper psychological realities for several characters. In this case, the ML's mystery doesn't actually have to do with the FL, but this drama has that thing you may like -- hidden dimensions.
Extraordinary You - super creative setup, with a lot of mystery around who and what people are. It's not a case of the ML tricking the FL - more that he tries to give her opportunities to awaken and see past superficial reality.
Sweet Stranger and Me - in some ways close to what you're looking for, but the ML isn't a devious type, and he deceives her in order to protect her. Major imbalance in terms of who knows what: he has the whole version of her family's past, while she's largely unaware.
