So like what I think that I have gotten fo far is that , sejin like seju ofc and seju knows , seju JUST killed a man who he knew pretty well and now he feels bad that he's become just like the thugs and sejin hates and he feels guilty that sejin likes him and thinks that he's not worth loving ,(hes just depressed) btw they were saying brother in the chapter right ,it's not brother it's his sister's revenge , I think it's a bit of a mistake with the translation, anyways yep
Bruh I'm actually telling you it was freaking hard to differentiate, have you seen the look alikeness of seju's boss and seju himself ? Other then their height difference I can't name something, they all have the same physical body and the same face structure, as an artist myself it was hard to differentiate
U still not get what am trying to say? You know that this chapter is started with sejin and a random man talking or u thought that random man is sejin himself but old version and then a men comes who u thought it was sejin with grey eyes lol ik u getting what was going on but still blamed on the art style not the translation

im still confused
