Crazy about Asian dramas

Sadistic Love is a love story about a boy who was adopted and then abandoned. The one who adopted him had a daughter who loved him. He came back into their lives to take revenge, and many hidden facts unfolded. He then realized how much she loved him. When he was abandoned, he met a boy, and they became good friends. But they later separated, and this gave rise to a misunderstanding between them. So, there were two parallel stories: one of revenge and another of misunderstanding.
Since I like watching love and romantic stories, I watched it completely. Otherwise, the drama didn’t have much to offer."
