I really liked this show.
It was really exciting and had the binge-factor.
The ending was really open, i do not know till this day if Jisoo is dead or not. But I especially liked the actor of Jisoo, he portrayed the emotions really well.
Gyuri was a cool character, many people disliked her but I think she was a very important role and was special for Jisoo. Even if she brought him a lot of trouble, they were into this together.
I recommend this show to people who like action, because there were scenes that could trigger people, like a lood of blood.
The OST‘s were sooo good, I liked them a lot and still listen to them like to normal music.
I would‘ve wished for a second season but it doesn‘t look like there will ever be one.
