This honestly feels like one of these comics that are based on the author having nice SCENE ideas, but no fucking idea how to make them into a cohesive and well written story.
Shame, really. It was very interesting based on the core plot.
The translations seem a bit off but that is definitely not the cause for the confusion.
usually when stories sum everything up in a few chapter, it means they're giving us the context for what the bulk of the story will be about, which I'm guessing is the MC's revenge as we saw in chapter 1. The chapters we've seen so far are back story for how he got there in the first place.
I can understand up to ch2 before things go through like lighting. Why so fast...this is not 1 hour movie. Come on...make many chs like..falling for risky season 1, getting heart for brother season 2, shits happen season 3 and get betrayed (which might be some misunderstanding as every BL) season 4 and husband chasing arc season 5....be like jinx...
