I know there's a thread for this, but it doesn't seem active/like the previous posts have been helped, so I thought I'd post here for better luck. It's a long shot because my memory is REALLY hazy, but I've been mulling over it for a while and decided to give this a shot. Can't hurt.
So it was a Korean? drama my mom was watching a few years ago. I sat with her for a few episodes before I got into kpop/dramas, watching bits and pieces, and she described parts I had missed, but I never knew what it was called. I've tried googling before too, but had no luck (I just probably didn't have enough...) I also can't ask her, because she watched it dubbed in another language so she would only remember the name in that language. Anyway! Here's what I can remember:
The story consisted of two brothers who I believe were separated at birth/when they were young. I also believe they came from a rich family, but one of the brothers went to a family that wasn't so well off. I want to say the other brother remained with his original family or was at least with a wealthy family. Some ahjussi type dude really didn't want the secret of the two brothers being related to get out. There's a lot of backstabbing involved I think...Gah. Now that I'm typing this out, I realize I really don't have much to go off of at all. I remember one of the leads being really handsome haha. Anyway, that was a terrible summary but if anyone has an idea, I'd really appreciate it!
