From what I read, they will have a happy ending. But can you really blame Ijun for acting the way he did. What I read(spoilers) he loved the main female char since they were young but never act on it since she suppose to marry his older brother. But that changed when Siyeon got a second chance at life and she was the one "went after" him and they dated. Then she broke up with him, basically saying she prefer the older brother for money/position(even though it was lie), then years later, he is forced to marry her, so he is bitter.
i will just read it if the mc gets a happy ending my heart just hurts too much with how ijun behaves I will see after it ends it just hurts too much
