I think Alex has long known that Clark is fucking with him to protect his ex, and now Alex has the proof he needed by seeing that ring on the psychiatrist's hand in the photo album. Alex probably feels jealous which I think will lead him to harm Clark's ex. Especially easy to do now that Alex knows where he lives. That dude is so dead lol.
I agree, I think everyone has a valid point about him killing people based on his rules buuut I think there could be a possible plot twist where his obsession with Clark leads him to do something unpredictable like harming his ex. Or, maybe Alex will manipulate the situation and use Clark's ex as bait to possibly harm Clark or maybe threaten him into "being" with him. This is such an interesting read, I just can't wait to see what happens next. Who will outsmart who???
Hands down one of the best yaoi I have ever read. Great plot, character development, art style...that is why I am sad its over, but I really loved how it ended. I wanted happiness for DG and Jiwon, I am glad they committed to each other and are moving in together. Big thank you to the author and the uploaders.
