As Mk got his monkey form he kept getting angry outbursts accidentally hurting his own friends... Mk tried not to though it only made him more stressed... One day he heard Sun Wukong talking to Nezha about sealing him away...he walked away since he didn't wanna get hurt furthermore...he was already insecure but this just makes it a lot worse (Time skip) One day Monkie king suddenly attacks him and tried pinning him down, he panicks and went to monkie form to fight his soon to be corner mentor... Soon the others arrived too and fought him... He defeated them... But for some reason he felt free.... Thrilled.... But then Mei slashed his other eye and stabbed him in the heart once he fell as she stares hatefully?.... Soon they can't even look at Mk and left...
Mk lived through that experience and tried finding somewhere else to live... Luckily Red Son for some reason allowed him to live at they're house though Red son's dad the demon bull king was skeptical, he still let Mk stay... It's been years since he's staying with the Demon bull family and he's a "bit" attached though he would never say it out loud... He's also mentored by Macaque now from time to time (The only people that knew of Mk bein alive are red son and he's family, also macaque) (in lmk the demon bull family canonically had a truce with the main cast) (kinda like the macaque situation.... He even lost an eye too!)
