Yeah the pacing is really weird. There's no way the assassin would wait that long to strike, unless Jiwha told him to? It's the only way it would make sense yet I have the feeling it's not that.
The assassin would probably wait it out to see his daily routines/habits before striking. Some get to know their victim first so they can pick the best time to do it without getting caught. Nakyum is with Seungho most of the time
It's been weeks at least. I think he learned all about his routine a while ago. Na-Kyum tried to escape once, why not kill him then? I hope it'll be explained.
If Seungho is an obstacle then, fine, the explanation holds up. But he knows all there is to know about Na-kyum activities by now.
Did I miss the resolution of that situation or something? I keep waiting to see the attack but nothing. Are these last chapters just buildup? I'm confused.
