There's a possibility Siwoo did that to make sure he does get expelled. IIRC, when his family's financial situation comes crashing apart, they still made sure/held onto Siwoo attending his current school (since it's a prestigious one). So logically, they wouldn't allow Siwoo to transfer somewhere else just because he wants to. He wants to force the school to expell him themself.
Y'all bitching in the comments saying it's weird when from the first chapter and summary it's already advertised as a pee fetish, yet y'all still decided to read it . If it disgusts you, then STOP reading it ffs. Y'all dig your own graves istg.
That's such a funny take cuz as I said, it's already given in the summary and chapter one what kind of manhwas this is. Additionally , each of the chapters literally starts with a warning note saying it dives with a certain fetish that people might not like. So if they're uncomfortable and knew they'll get disgusted/weirded out with the premise, then they should've avoided it. It's not the author's fault they still decided to read it, no? ╮( ̄▽ ̄)╭
