I dont remember but is the red hair the ex of the main character? Or is he just a side villain
He is a typical bully with no personality. He bullied someone he thought was weaker than him to feel better about his shitty self. That person ended up being a different league than him and so strong that he could shit his pants (special alpha). His father wants him to get along with him (not knowing what his son did to him in high school), cause he is an heir to a super powerful family that could be useful to the son and his fathers family in business. Dude is triggered that he has to be friendly with someone he still cannot accept due to his inferiority complex and lack of personality that he is reminded of when he sees that dude, so he just uses his two braincells to come up with a way to mess with that guy instead. Even though he hears stories and SAW with his own eyes, how that guy literally handles anyone that messes with him and gets away scot free cause he is THAT powerful, dude still goes on. He is now (spoiler) kidnapping his first love using his nobody of a step-brother. He is just a plot device, but an annoying one.
Thank a lot haha i was confused because of the latest update but this clearls it up (づ￣ ³￣)づ
the read head is such an annoying ass side piece just to show us what happens in Kim shins life when he isn't with MC. His character is so dumb and useless. Like bruh....
