other than the issues you mentioned, it's bc they liked the art and the story in the beginning and developed expectations based on that, and the later chapters just didn't match up to that.
about other manhwas, it's partly bc antagonists are usually portrayed in media as "ugly" and shabby, and partly bc SOME ppl like to ignore red flags when it's about a good-looking person (maybe they're into criminals, maybe they have other mental health issues or maybe they're only focusing on their looks (pretty privilege) idk)
Yeah it felt like the only hope they got was the art and it was changed. What you said is definitely true. I still don't get why some readers like those kind of things. I have friends that love manhwas with toxic handsome red flags but I will never get why. Hope it's only on the comics tho and not in real life coz boy they be needin' therapy.
There's no connection between protagonists, everything comes out of nowhere, the plot line is never followed, for me there's no development and it's messy, but I respect if you liked it this is just my personal point of view, I'm not saying this one of the worsts out there but definitely stays on worst tier for me

This is hilarious af, i don't get why you guys don't like it? Except for the fact that they changed the artstyle, take depression and suicide lightly, there's no chemistry, and the relationship feels forced, what problems are there? I think it's great and it's just like any other BL I read. It's getting too much hate, can someone explain what's wrong with it? I was just enjoying reading this because it was so funny but then when I looked at the comments I was super shocked at how much 1 star there is. I was even thinking if I was in the right comment section.
And I know I don't have the rights to say this as I'm still not yet finished reading, I haven't reached the end yet so I can't say anything about it.
