He will tell her anything. He will grant whatever her heart desires, whatever she wishes. Rhys would do anything for this girl. But, there was one thing he couldn't grant her. The happiness of being together with another man. A man that isn't him. Lately he is troubled by it greatly. He wants to help Kazuya, it's better if she goes to him.
