i'm only on chapter 8 but it seem like everything was kinda handed to him, even the red hair girl feeling for him was too quick and it didn't make any sense, yes he did "train" but that was just running around for a few day and suddenly he's able to defeat 2 person who has been training since probably birth, ig we could say the system help him but it just didn't seem like he earn anything yet.
At this point I really don't know if Hyeon love Yiseon, or if he just want to control him, they have their sweet moment but Yiseon seem so easily manipulated by everyone around him, and the person who know that best is Hyeon, he's obviously a big walking red flag, how he view their relationship remind me of people that have commitment issue.
