Rin is a cold man. he doesn't talk much except for important matters or with his family only. he is a hard worker. he put his job before anything else in his life. he spent a lot of time in Spain to study, thus making him a smart and intelligent man, that's why his dad told him to took over his company. Rin is very difficult to express his feelings, there is also a sense of pride that prevents him from speaking honestly about what he feels.
