Hmm, I mean would there be a better ending? Like as in a cheesy ending wouldn't really fit the style, as much as it would seem nice. If the story ended with just them hugging or with an "I love you"+ extras and without the ending, I think many people would be happier even though that doesn't make much sense?
There's a lot of holes in the story but I feel like explaining it all would be too much?
We already know most of it except what happened in between when Woojin left to now?
I don't think a cliche ending would do it either.
Also it's a continuation of this conversation if it'll make more sense to you: http://www.mangago.zone/read-manga/geu_kkeute_issneun_geos/uu/geu_kkeute_issneun_geos-chapter-47/10/
Hopefully a few extras will clear it up or at least give more of the romance aspect into it?
I'm pretty sure it was hard for the author to come up with a nice not too lame/cliche ending, as the demand for chapters kept growing.
"The ending sucks, I know, but I was sick of working on it. I'll make some crappy follow-up stories next month. #Sorrynotsorry
Worst. Ending. Ever.
