Rin seems to respect almost nobody. He will only acknowledge your presence if you have a noticeable and annoying ability/influence on the soccer field. He seems to have no friends, only rivals. As your boyfriend, he tends to show you his love through acts of service and physical touch in private. He's very possessive and can get jealous easily. He would do anything for you to stay with him. He's stoic and serious, but his eyes seem to always light up when he's with you.
