Cowards, no better word to describe them. They are running away from responsibility of committing to one side so they don't get hate from the other side.
Like in this one, just a few ch ago FMC wanted MC to break up with her, he was very much against it! Then he breaks up with her out of nowhere, just to drag her back in 5 years later. Like, what!? Make up your mind god damn coward! But no, "i'll just leave an open ending so you guys can figure it out on your own"...
How does this even go past the editors? Are JP people satisfied with open endings? I just don't get it.
