I think story lacked story wise, I think Ji Min and Hae In were amazing, but these adult dramas normally lack plot. They faced realistic issues together, but it seemed the drama wasn't really thought out completly and they wasted a lot of time on the same issues throught the drama. Therefore, it felt very repetitive throught and boring, until the final epsiodes that they actually solved them. I think if they put a little more thought into other plot lines it would've been more interesting. I also think that both actors lacked chemistry, they both seemed like bland characters, they could've worked a bit harder on their personalities to at least drive the story. Shame, because all the OSTs are fantastic, it was one of the best things that came out of it.
