This was one of the best dramas of 2017. Include the perfect cast, perfect couple, a great amount of comedy, a great amount of romance, and the perfect amount of mystery. I like that their was a second lead and he did like the main actress but didn't ruin/try to ruin other relationships. The problem of many law/police dramas is that it gets boring after a few episode as they are mainly solving cases. This wasn't a problem in this show as they focused on many aspects and this show had both a continuous and per episode story. The main couple were perfect, they were realistic (they didn't hide their flaws) and the chemistry was amazing.  I was excited to watch each episode and I knew i couldn't skip any scene as it came out once a week.  request: while watching don't skip, it's wort every moment!. I also like how the younger brother had a story (not gonna ruin it for you). This would be the top drama of 2017. I love bae suzy, lee jong suk and jung hae in ! also watch a few episodes before stopping , but i think the first episode should be enough to get you hooked. There was just one thing I didn't get, how dream could be so specific that they would never give the answer but if you just ignore the realism of the dreams, this drama is great.
