ohhhhh I finally get the plot it just clicked
basically seung-hyun gave yuta a terminal injury to his head (you’ll see next chapter how he gets this injury.) and right after he receives said injury sh makes a promise to yt he’ll come back to help/save him after he defeats the people coming after them.. spoiler alert he never comes back and yt has always held a grudge since this incident and he’s willing to do anything to get back at him for it (hence forth why all this beef between them is going on)





happy pride month to these two specifically
