my favorite characters were Kyung Po, Don Hyuk, Jung Hee and Park Choong Jae. the acting overall was nice, but the main characters felt flat.
also, the romance was unnecessary for the 2 mains and Kyung Po (honestly he deserved better), he was the one who befriended the "ninja" no one saw, but still they did not appreciated him and made shallow remarks about his looks.
also, since they were "young and naive" I'd say the flat romance could be overlooked, but it'd have been better as just "unexpected friendships".


the plot about friendship and youth was solid, but the delivery was lacking. tbh even though it's only 4 one hour eps, it felt too long and I found myself playing at my phone most of the time.


and basically the mystery part was exactly what it looked like in the 1st ep, so they wasted alot of time "trying to find the truth".
the ost was nice and I never rewatch things ;p
