I think you may need to reread the story again lol, his behavior was not really out of nowhere- sehyuk was always the type to do what he wants
i got the feeling he kinda changed in the sense of being more open to listen to hamin and stuff. was also expecting the side stories to be something like both of them fighting gangster and going on dates haha. sehyuk being "the mad dog" from the organization but who now only listens to hamin.
i guess i could've read it all wrong.
Hm to me, I personally don’t think he changed much. I barely saw development, it felt more like the main story was focused on the action or getting them to finally be together rather than focusing on his character development
hmm I see your point, I am taking this pov into consideration now
mad dog had a good plot and the author had established a nice dynamic for the main couple. by the end hamin is much more assertive and mature, which made me feel like he and sehyuk would be a nice pair.
so why the fck is that out of nowhere sehyuk step all over hamin's boundaries???
nothing is gwenchana.
