it's weird to explain but i get it, I had a reason like that too but rather than thinking "he will survive the rumor" I think it's best to put into perspective the pride as a awakener and how you're the one ruining a man's entire legacy, the one you admire and has been with you for so long in a weird world.
even if it's just a rumor, the thought of tarnishing the image of what's almost like a father figure or letting him down after all the trust and effort he put in you.... just bc of your lack of power and foolishness? it'd be best to be defeated and die with honor
Firstly his girl is the most powerful ranker in Korea, she would survive the 4 minutes it would take to go get back up! Secondly he really should start listening to people that have been in the game longer than him. Because he is a liability all things considered and may distract his girl from going all out. Thirdly "dying with honor" THERE IS NO DYING WITH HONOR! HES 18! He would not even be the dishonored one, the one that's being rude is the girl challenging him! It was even said that's she's out of order many times!!!!

What is the obsession with honor Dawg you've been tortured for Kayden I'm sure he'll survive a rumor that his disciple is weak. Its crazy how he'll lowkey put everyone in danger cuz of his pride. You'd think because he was so passive he'd ACTUALLY LISTEN TO OTHERS!
