My Daughter Seo Young- The main lead is deceived into thinking that her father is dead. It's hard to explain, but in the drama he is the one who is completely in love with her, and throughout the drama he's uncertain if she even loves him.
Woody Sambo- She is physically stronger than him. He tries unsuccessfully to break down a door that she just smashes through. She ends up protecting him a few times through the series.
Mook Liam Petch- She's an interpol officer, and she starts to pretend to date him because he's someone she suspects stole a diamond necklace. This is a Thai drama, but it is not slap kiss.
Golden Bride- She starts off her relationship with him as more of a nurse than a wife, so he does depend on her.
Hear Me- It's a movie, not a drama, but he does literally follow her around, start delivering food where he thinks she'll be, and she just generally motivates him.
These kind of fit but not completely:
Leh Nangfah- She does own the company, but she does need his help to run the company and help her because her uncle is trying to take it over.
Stars Falling From the Sky- She deceives him into letting her stay with him (he thinks it's just her in reality she has 5 other siblings she's hiding from him). She gets torn down a lot in the beginning of the drama, but she becomes stronger and insists on taking care of her siblings.
Me too, Flower!- she's a cop, and she begins the drama emotionally unavailable and distant, especially to her family, basically the way you'd expect a male lead to be like at the beginning of a drama.
