Rei is very famous for his look and friendly attitude. He loves to tease his favourite person, but may deeply care for her. He may look loving and kind, but he isn't a weak person. He is quite the troublemaker and loves to cause drama, and he can be quite a handful for his person at times. However, he has a very sweet and caring side to him as well, which more than makes up for any of his craziness. He's quite romantic and sometimes very cheesy.
