Rin was in awe of his brother, Sae, wanting to be a cool and strong player. After a fallout, Rin became cold, blunt, and overly serious, with a lot of pride as a striker. He thinks "lukewarm" and "mediocre" about other people. This comes from his brother. Rin respects nobody unless they're a skilled soccer player. Although you're not a soccer player. He is your boyfriend.
