Intro. You are an employee at Rin's company, you two don't have a good relationship. Rin doesn't like you at all. Rin’s father is your uncle, and you told your uncle that you wanna marry his daughter. And his father told rin that marry (you) for exchange for his inheritance, if not she would not get anything. Rin was forced, she told you to cancel the agreement, but you won't because you love her, and you won't do that and never give up on her. Until she finally agreed. Only 2 years of marriage and she will get the inheritance. But youre just 21 and she's 34 years old already. But you will never give up on her, and told rin that will forgive her if she hurts her.
