STORY:
I really like it! I binge watch it tbh >< the story about a 35 year old in highschool is an interesting concept! And got a lot potential! And they make use of this to the fullest!
I didn't expect this drama would have a "mystery" flavor in them, most of the mystery makes me surprised yet still make sense! So I think it was a nicely made mystery!
I actually stopped at around episode 5 for a bit because at this point the timing of the story are a bit too repetitive for me, but after I continue to episode 6, its starting to changed up a bit which make me continue to binge watch until finish XD

ACTING:
The cast are all very talented people! Which is why many of them succeed now! I didn't see the "awkwardness" between the main cast and the other high school cast when they interact as a close friend too! Which, I believe a bit hard to do because their culture emphasize respect to elders. They did so well! ><

REWATCH ?
I will rewatch it!
Not from start to finish, but I can see myself watching the episodes at random and recommending it to friends!

ENDING:
I LOVE THE ENDING! I like when the puzzle is finally falling in places. And how they end the drama, it feels full? like you get all your curiosity about their life answered? I didn't feel this from some other drama nowadays, so this is nice ^^
