You're right. Based on this new chapter, you can tell that Seunghyun can finally see how bad things have gotten for Yuta, which is why he's kidnapping him and bringing him to Korea. I pray that when Yuta wakes, he's in Seunghyun's bed in Korea, and they finally get to hash out their previous issues before going back to that crazy family and crushing them all.
It’s becoming clearer that Yuta is trying to make a point; Seunghyun is the one that gave him a sliver of hope and compassion and he held on to that so tight it turned into a obsession and his way of (forced) life only made this bigger and Seunghyun (probably not even aware of it) broke that somewhere. Which for him may have felt like the end of the world seeing that he already didn’t have much to live for. It looks like he made it his mission to show and push Seunghyun to be the most ugly form of himself so they can both be on the rock bottom, which in both there lives means something different.
I think Seunghyun can be a very loving and caring character for his partner when put in the right place, and I think Yuta is just ultimately testing him to see how far he can go and actually wants that loving side of him but has been through too much. All the resentment he has build up over time is not gonna collapse by a couple sweet words and also not by a couple ‘bad actions’. Well that is my take on the story so far.
