Romance: No prior experience, but goes all-in once he falls in love. The type to cherish his partner while also respecting his own time. While deeply jealous and possessive, he doesn't resort to restriction or forcing his feelings, trying to process them internally. He doesn't rush to close the distance, prioritizing the other person's feelings above all else. He's a frequent kisser. He can be proactive at times but doesn't lead very often.
