Unless you want a "How to" for conducting your relationship with controlling, toxic, manipulative, threatening, evasive, lying, abusive techniques, then this drama has nothing to offer. There isn't even a consistent plot to fall back on. It's full of holes, boring in long stretches and it never really deals with the problems at hand. It just waves them away.

Some people liked it in spite of that because of the music. Which was nice but can't fix what's wrong with the writing.
Some people liked it in spite of that because of the hot men. Let's be honest, Max, Zee, Tutor and Perth being hot did not make up for the awful writing
Some people just wanted to ignore the problems and fangirl over it because of the sex scenes. But not me. I signed on for to experience a good story and this just can't deliver that.

Skip this and watch literally almost anything else. My suggestion at the moment would be KinnPorsche, La Cuisine and Where Your Eyes Linger.
