I don't know how to cover up spoilers, but just saying - shame on the guy who thinks he's the top dog just because he sneaked in at the last minute to attack someone who's fought everyone else and is tired AF.
I sorta liked the concept but the plot is stuffed with fan-favorite shitty drama like:
"I banish you for your own sake but won't tell you the reason so you'll hate me for years"
"The guy who told me to get revenge is actually the one who killed my parents"
"In order to rival the MC I allow some creepy guy to modify my body"
