I remember it being all colored, not sure what it was about but the girl was adopted. She looked beautiful - you know, dark haired, blue eyes I think. She had brothers? I'm trying to remember because it was a great read but there were only 30 something chapters out at the time.

What now?

OMG it has to be Lan Chi!
It's ongoing and they have recently came out with new chapter releases!
It's one of my favorites and its a manhua not a manhwa lol
