Mistress

With what OCN have done with the drama, I found it hard to justify adding the 18+ rating. There was a slight skinship and one quick 30 second vague intimate scene in the first 2 episodes and that was it. The usual bait and switch tactic. Admittedly, it was one of the better attempts from OCN when it comes to creating a mystery drama. However, it quickly went downhill. It felt like the writers were stuffing up the mystery to make it as big as possible, with twists and turns that were more like cheap thrills than actual surprises. It became too bloated to make something coherent. It was hard for the drama to juggle between all of the 4 main characters and their interconnected stories which also affected the dynamic between the four of them. You can notice who ended up being the fourth wheel.
