JJ raises my blood pressure seeing how he keeps harassing the MC but I also don't think he's an asshole since objectively, what he's doing is childish and not really bullying. He's constantly teasing the MC yeah, but since we are looking through the MC's perspective, it looks like bullying since we know that MC gets easily agitated when things stray from schedule. Honestly I feel like the MC did nothing wrong even if he comes off as harsh and rude due to his bluntness. He's just living his life at his own pace. JJ makes my blood boil since his plan of shoving his way into MC's life is working and I'm not here for it when the MC gets so distressed and paranoid, lowkey not used to his peaceful life anymore. I'm so worried that once MC gets time alone away from JJ, he's going to start """falling in love""", being confused why he feels out of sorts without JJ around, be more conscious of JJ, maybe some gay panic when JJ does something, overall mistaking his discomfort during the period of getting back into his usual pattern as discomfort for JJ not being around.
Chances are it won't be this predictable since on novelupdates, there's the smut tag hehe. I really wonder how it'll develop to that point, except the manhwa will show none of it.
