I am not really a horror person so when I first went into this, I was a little nervous. I don’t do well with jump scares or anything scary but I had very little trouble with this. So if horror isn’t typically your genre, I would still recommend you give this a try. Unless you’re super squeamish then I’d recommend you steer clear.
So I went into this with knowledge of the ending/big twist but it didn’t hinder my enjoyment at all. It was really interesting thinking about what would come next, how they would get out of each door, what the taboos were and who would die. Speaking of death, I think I cried harder at this drama than I’ve cried at any other contemporary cdrama like ever. I actually had to pause a few times just to sob because I was crying so hard I couldn’t see anything. I am dead inside. As for the bromance aspect of the show, I really enjoyed it. They were cute and funny and honestly soulmates. I do have mixed feelings about the ending because while it can technically be called a happy ending, I would classify it as ambiguous. A little bit like the ending of Guardian, though perhaps not as depressing. Happy enough but if you think about it, there are too many unanswered questions for me to be content.
Over all, I super recommend this. The acting is great, the story is intriguing, and the OST is pretty good. 10/10
