I was hooked at episode 1 and absolutely love this series. I think the male lead is exactly who he is supposed to be, and is great. The obsession that comes from a toxic relationship is real and can last for years. If you have not been in a toxic relationship, you are lucky, but this is maybe not for you - I imagine you can't relate with the female leads at all. I can, and I am so happy to see a show where the girl can't and won't change the guy...you know like in real life. I have not read the books but I will after the series so I am not sure how closely it follows the written storyline. Can't wait for Ep 5.
