At first when I read this, it's kinda giving Victor x Yuri
The world building is bad, the source of power is ambiguous, no clear sign and reason of why everyone is manifesting. Also if the root of their rivalry is so deep that makes them kill each other, ain't no way they just reconcile like that. Also I can't believe he's in love with the person who murder his colleagues and harming his own mother.
I feel like there's too much going on, the plot is kinda messy and emotional scene doesn't really feels that emotional *well obviously because this is comedy?. But like, I feel the author wanted to make a lot of different incidents and stuffs, but it feels forced. For example jumping into emotional scene so suddenly, or when someone is really miserable it didn't really feels like it because of the drawing style is too cute. I said this not because I hate this manhua, I respect the artist because it took a lot of effort for making this manhua. I just want to point something that can be improved, it's good but the author kinda need a lil bit help from a Webtoon editor.
I'm fine with any artstyle or bad drawing as long as the story is good. But the artstyle change and also the coloring?! I'm surprised it could pass the editorial team to be published, as an artist who work on a Webtoon company this is so hard to read
