The Author hasn't moved on from BJ Alex plot, and is still reliving those moments in this manhwa. Kim Dan did that position just like Donggyun and JK had the same reaction as BJ Alex when Donggyun had led the segs when they made up. The author don't know how to make an appetizing scene anymore, they just mostly recycled BJ Alex so they could milk it again.
Am sorry, I just feel like things could be better. I mean the author has promised a very much intense chasing arc for JK when this manhwa was on Hiatus. And after that long Hiatus, I thought they would come up with a better plot. I even thought maybe there would be a timeskip, you know, to allow Kim Dan to heal and have his forgiving nature make more sense.
I still don't like Jaekyung, I just can't like him at all. Am very sorry. I'll read this again when it's finished. And I'll decide if it's worth to read. For now I'll erase this manhwa from my memory. Sorry if some of you guys get offended. Apologies.
Happy reading guys~

What in the BJ Alex make up sex is this?
