Something like the lead would hurt the other lead and end up falling in love with her. The closest drama I could think about is Secret.

Please recommend some dramas of this kind. Thanks!!

I think these might fit your criteria:

- Beyond the Clouds
- Cruel City
- A Love to Kill

You can try searching the forum, too. I think people have recommended many revenge Kdramas before.
@Eliza great!I searched for this kind of Drama to.Thank you :D
