That's what we call character develop, which seems to be lacking in so many manga. At first we judged him on his bad actions, but the more we got to know him the better we understand him. At the same time DaYeol has reached out to him, which has helped him grow as a character.
I know - i love it so much we need more stuff like this
I beg to differ, in manhwa or webtoon which usually has more chapters than average mangasm it is easy to find some character developments...albeit in yaoi it is sometimes for the worse instead of better...like a tough and independent uke getting more and more clingy and timid the more it goes on, which is irritating..
Yet, manga usually only has like 5-7 of main chapters so hence why it's usually a quick resolve of plot without getting deeper to any character studies
