The new chapter is up on Lezhin Comics, and it's not as bad as ppl think, lol. Even I was off with my predictions (at least so far).
Spoiler!
Potato is a 20-year-old super fanboy/admirer who looks up to Jaekyung as a fighter. The chapter is kinda funny, lol. He's actually super adorable, and jealous in the most juvenile way possible. I won't say anymore, but him finding out about them could be a potential issue.
@artsy_amusing I told you guys potato just has a boy crush on Jaekyung because he admires him so much lol. But after his discovery, I wonder if his feelings will remain the same...
