It's a contract based marriage drama.
He wanted to get marry with her because his father wanted to do so actually his father was her father's friend her father helped his father a lot in bad times. So his father wanted him to get marry with her so she have never been in pain and in this way he protect her. He forced her to marry but she didn't want . Then something had happened , he didn't want to get marry with her but she wanted because she was in problem. Here I didn't understand the track of the drama , he ready for contract marriage to help her and to show his mother but his mother only told him that he didn't need to get marry her just inorder to protector he can protect her without marry her . So why there was a need to contract marriage . They can started love story as a boss and assistant or boss and an employee relationship. They had misunderstanding regarding her drawing so in that way they can started the story.
Secondly male lead had same type of expressions all the time . This made boring
