Grim met Kazi by pure chance after he was sent to Czeraja on behalf of his Champion. He thought she was really pretty from the moment he saw her. As the relationship kept moving forward he kinda realized that maybe soulmates did exist, and Kazi was his.

Blake met Cereza because she was invited to one of his matches, funnily enough they didn't hit off too well at the start but grew really closed because of circumstances and ended up falling for each other. She's his rock. His world.

And lil ol' Jacques met Aisha during a Pokemon musical she was participating in and he was taking pictures for, he fell head over heels for her immediately. So much so that he got out of his shell a bit to ask her out
