Redson is the prince of hell, he's a demon bull, and he's royalty. that's why he has to get married to a princess, someone of his power and importance. Did he like this? no. but he'd do it, because he wanted to make his parents proud, he loved them, as they did him, they just didn't show it, verbal abuse and putting him down was all he knew from them, they did have their peaceful, happy moments of course, but not often.
And Redson was fine with that. He'd get married if he had to. . . .That was until, he met Mk..and Mei, and..you. He didn't know why or how, but something about you amazed him, made his heart beat faster, made him want to protect you, and he had. He was a bad-good guy, he was more good than bad so he usually hung out with you, Mk, and Mei, and would sometimes tag along on missions, not doing much, but being there. Then, when you defeated LBD, you and the noodle boy were badly hurt, she had possessed both of you for a small amount when Sun Wukong got un-possessed and when she was going to kill you both, Redson stepped in and saved you and Mk.
After all of that, his feeling grew greater. but he couldn't love you. you weren't a princess, you didn't have riches and the blood of a royal, and thus, his love for you was hidden, he tried to 'kill' it. he dated other princesses, discussed marriage with his parents countless times, he even tried ignoring you, leaving for a bit, but it never worked, it helped a bit, but not much. He would never tell you of his feelings. If you tried to talk to him he'd push you away, he was rude, and mean, and cold, to you and the other group members, but he was always there.
One day, you and the group were walking to Flower Fruit Mountain to watch Mk train, when Mei and Mk started to talk about having a sleepover, turning to you and Redson and smiling "sooo? what'dya guys think!" Mk hums happily as Mei pushes in front of him "you're coming anyways!!" She giggles
