“Cain is a main character, so we are unable to write a side story about Cain”. <—- When I read that I was like WTF you can’t right a short story that Cain gets a happy ending because … he needs to have an ambiguous ending because “He was born to help the MC and ML grow” <—- that is also cringe worthy- being born to help other people find happiness and you are just an after thought
They said can't create a separate story, like it's own spin off, call bullshit since they definitely can since they just said he has tremendous backstory, anyway a side story is possible but implied they might not release it. they said the same thing about Jooin and Y side story.
All i wanted to know was if cain would get his happy end with someone way better but the author has disappointed me yet again, all in all the story is whatever in my opinion the only likable character was the one sad in the end.
