I just wanna tell all the people who haven't seen it yet, that the epilouge/creator's note is available on lezhin for free and I read it and she answered some questions but she didn't specify whether or not bum died or if sangwoo is really dead. She may create a new comic but she's not sure. I'm pretty sure the comic is officially over though. Its really sad how such an amazing comic ended so terribly.
I mean I can see why itd be unsatisfying, but I think I'm used to open endings and forming my own conclusions. My theory is that Bum died, possibly because Bae ran him over, and therefore didn't go to jail, instead opting to chase after Sangwoo (who he's not over despite his claims) and ends up fulfilling the viewpoint of "being joined in death"
Guys we get that it's free on webtoons and supports the author. I used to read it on there. But some ppl have situations where they can't download it (like me) so please don't get mad if some pop wanna read it on this website
