Edit: Nvm found it

I forget the name, but there's this romance webtoon where a half-russian orphan girl is taken in by a chaebol family because the grandfather felt indebted to her grandfather or used to work for him or something, and then he made it so the only way his actual grandkids could inherit his fortune is if they marry her, which is how she and the ml get together, and the ml is super gentle and the only one in the family besides the grandfather who treats the girl like she's his superior.

Does anyone remember the title?

please edit in the name of the webtoon, after you find it.
