once i read a cn novel where the mc was injured and was going to hide in a village, for fun he started teaching a young man the same way that old man teaches, in the end the young man had a muscle problem, injured for life mc just laughed, from the beginning he knew he was destroying the young man's dreams , but he did it just for fun because the young man didn't doubt him
so the mc of this webtoon is really good and consistent, he complains and etc, because it is common sense that these things that the old man forces him to do, only make him worse and the old man doesn’t explain. Anyway, I don't think it's fair to have a lot of comments complaining about the MC or making fun of him because he doesn't want to train or do what the old man says
