Except for the last two episodes where the ending felt weak and rushed (less intelligent and less interesting) this story is good especially the first 10 episodes are phenomenal! I would recommend this to anyone who liked watching kdramas like Descendants of the Sun but don't expect a smart epic ending. Watch this for the friendships, the training shown and the strong villain and all details shown in investigations.
All 14 episodes made me want to watch and see what will happen next. How our heroes will deal with their training and then how they will deal with the Villain who hurt them and so many others and you will be on the edge of your seat wanting to binge watch the show till EP 15. The Romances are well developed, the Friendships are awesome, The Training shown is seriously amazing. The best ep is the Sports day in Ep 7 and 8 I think.
