The change is Hyeseong's looks, not his hair, but how he seemed to shrink in height in the first series was a bit odd. And now in this one he looks like a kid, in comparison to how he was introduced as the adult Hyeseong in If you hate me so much. I wonder if the comments about Hysesong would be different, if he was presented looking like how he did originally, which as you said, was more like how Dojin's friend appears.
Okay, so I love this chapter (ch 23), and I have a very specific reason why.
So I mentioned this back the raw for this chapter came out, but it was with this chapter that I REALLY noticed that Dojin's friend Heesu looks a LOT like Hyesung's orignal design. Only with his hair parted in the opposite direction.
For those who don't know- I refer to this http://www.mangago.me/read-manga/if_you_hate_me_that_much/uu/6ddb5c2dc9b0bff0/Ch8/pg-12/
So anyways, the result of this is that Chapter 23 of THIS story basically looks like OrgDesgin HyeSung and new design are just bickering it out XD . It's pretty great.
I'm not sure if the author did this INTENTIONALLY, (though I kinda suspect they did), but I love it nonetheless.
About the actual content of the chapter. Hey, I still love both Dojin AND Hyesung. Lots of people going "HyeSung is so meaaan!" , but really, I just find him to be spunky and hilarious. Besides that, I'm pretty sure DOJIN digs that spoiled bratty side of Hyesung. Some guys are just into that.
Remember, Dojin's spent most of his life with pretty much everyone either sucking up to him or being competitive with him. A fiesty little guy like Hyesung is probably a breath of fresh air to the guy.
And also, on Hyesung's side, yeah, he's having fun! Little dude enjoys being pampered and Doujin likes pampering. I'm happy for them.
