I am a fan of HS dramas but this was a cut above. The actors, especially the two leads were strong, subtle respondents to each other, so in tune with each others personas. The sweetness and goodness of their characters was so nice to watch. I would love to see them at 25 to see how they fare in life.
A MUST WATCH!!! I fell in love with OSW and KHG. This drama got me hooked from the first episode! The acting from every single cast member is excellent! OSW especially is a revelation to me. I never followed Wanna One so I didn't really know him, but I'm now a huge fan. His acting really shines in the small, quiet moments (like that "just a prank" scene where he confronts Hwi Young in the back of the school). KHG is also fabulous as the female lead. Of course, we already know she has the acting chops. Her chemistry with OSW is electric!. What I like about the plot is the slow (or maybe not-so-slow) reveal of what each character is going through.
