I'm gonna be honest, so far I couldn't give 2 damns about the teens and their storyline.

Too much focus on the will they-won't they romance and the typical teen drama arcs (school bullying, teen angst and rebellion against parents, accepting oneself) which completely doesn't go well with the extremely serious and thrilling plot of the 'adult storyline' full of spies, murders, hunting people for their abilities, betrayal and the John Wick style of trying to survive.

In my opinion, show would be 10/10 if you removed all of the teen stuff and focused on the parents instead and lean into the teens' pov at the last few episodes, instead of the other way around. I'm way more interested in Lee Minhyun's, Kim Doosik's, Lee Jaeman's and Jang Juwon's characters than their kids - Lee Kang Hoon maybe being the exception because I find his family's story particularly touching and heart breaking.

As of now, I really cannot go through the scenes with the teenagers. It's just too boring when compared to every scene with the adults. If you go into watching this expecting a lot of action, then be prepared to skip a lot of scenes of teens running around with a crush.
