Hello! Can anyone help me find this story I didn't even know the name of. I just remember a bits of that story. Of course the male lead was a rich man like all other typical story and I don't remember anything about the female lead. Anyways, Mr. Whatever was in love with his adoptive sister and she loved him too. But their parents didn't approve their relationship as they were brother and sisters in front of others. So they (their parents) forced and threatened them to stay away from each other. And now that he was trying to move on with someone (I forgot her name but she is the lead female character) in his life, his adoptive sister is back and was trying to create misunderstandings between them because according to her he was only hers and no one else. That's all I can remember about the story.
Plz can anyone tell me about that book name like pretty plz
P. S Don't mind my English it's not my native language
