I enjoyed watching the series. I like how there wasn't just one bad guy that controls everything but multiple, showing how the world used to work. It almost had me forget that it was a retrospection of Yeonghan's memories.
Nearly cried at the end cus he was all left alone when his friends and colleagues have already passed away.

Its a nice show to watch and keep you occupied with his own amazing story. There's action, drama and a little bit of romance. I recommend.

Thank you for reading my review.
