well NO SHIT. This isn't a fucking fairy tale. Life doesn't end on a happy note forever. Every chapter of a new start in your life comes with trials, as I'm sure will be the same for them. The objective wasn't for them to get a fairy tale ending. It was to grow, to accept, to learn to be at peace, to know it's 'okay', and especially for Jaeha it was to understand that it's okay for him to love himself and then love someone. Did you even understand the story? How are you disappointed??
Is there something wrong with wanting to see how they, as a more or less stable couple, try to concur real life problems that were major factors in the story?
But aren't thay back to how things were before they broke up? So theyll have to face the problems jaeha wanted to avoid that caused the whole catastrophic misunderstanding. I'm disappointed that this won't be part of the resolution but at least they're happy again with no misunderstandings..... ╮(￣▽￣)╭
