I believe it simply just bothers ppl how Kangwoo was treated, I mean we all acknowledge how shitty it was for Jeonghan to simply break up and not really explain to Kangwoo why he didn't want to be together. But then again, some ppl may not comprehend it because they either haven't been/dealt with a situation yet or cause their too young to understand.
The big issue in this was communication...I'm 26 and I been in similar situations like both Jeonghan and Kangwoo place, so I can relate to how they feel and how things went down for them. However, I've always was willing to communicate and I've always stood up for myself and never allowed someone to fully treat me how Jeonghan treated Kangwoo. It was just the other parties didn't want to communicate and I never allowed anyone to treat me like Jeonghan was treated by his family and by Mr.An. I always expressed my feelings, but for whatever reason the ppl I've dealt with in my life just thought it was okay to walk away and be shitty/weridos. So, I kept my feelings to myself and simply continued to carry on in life too, walking away too. In the end I realized that life is to short to dwell on wondering why ppl act the way they do or constantly wondering what I did wrong just because they don't how to communicate. If I meant to be with someone, I believe the universe or God will allow it. Ya know ...its life. You just gotta test drive some cars before you finally get the right one. Of course some cars will be horrible and may crash your heart but you just have to be true to yourself and keep on pushing it

I remember one time long ago, a crazy ex of mine and I we're getting ready to play patty cake, and he said "Do you know what we're about to do?". I remember I looked at him, lifted my right hand ever so slightly....and pimped slapped him then pinned him down and yelled "WE FINNA WRESTLE BOY". Lmao after an intense hours of tickle fights, fake fighting,and pattying some cakes, I defeated him in both wrestling and patty cake!!!! (Well we both won patty cake its a equal opportunity winning game) Had to break up with him because of his crazy possessive side but that scene in chapter 5 made me remember this lmao. Lord have mercy on me
Yakuza guy pretty much said "TOOT DAT ASS UP BIG FELLA"
