It's very obvious that they still have a long way to go as Mingwa mentioned there lol so yes gotta have patience. Also jjk does care for the MC just that it's not too overt. For example in the recent chap he went out to check on Dan and defended him which is very unusual for a character like jjk... Is it bear minimum? Ofcourse but as I said one ought be patient and observant that's it.
I just pointed out the main reason that it's a slow burn bruh it's been only 40 chapters. If you think there has been absolutely so changes and still everything is same as it was in chapter 1 then that's on you and your reading comprehension. I just suggested you an easy option since it seems like you are not feeling it lmao so calm down.

I usually like toxic MLs, but I dislike this one so much. Is it because it feels like he doesn’t really care for MC? Why is this toxic more toxic than usual?
Explain it to me, please
