It's sci-fi and it's cool sci-fi. I dont want to post spoilers but it is totally worth watching more than once. The acting is really good and the OST released for the series is so beautiful it has a very haunting vibe. I saw posts say season 2 is probably going to happen and im happy about that. This series deserves longer episodes the writers created a great story and the actors nailed their roles. I really liked it.
