I didn't really think much while going into this show.I was mainly watching for the people who I already knew and liked before which included Do-yeon,BiBi,Ye-na,JaeJae.So basically everyone I knew before except Ji-yoon,so I was unsure how they would all fit together but it was unexpectedly wonderful seeing the cast play their charcters and their chemistry and banter slowly growing throughout the show.I've seen people talking about it being too slow but it truly is slow at the start to set up the world and once it picks up,it's like you're on a rollercoaster with the cast with all the discoveries and plottwists.This show hits the perfect balance in comedy and mystery and felt almost like watching a Scooby-doo series set in a school.Obviously the world in this show is way larger and its really interesting to see the plot untangle itself.Refering back to the Scooby-doo thing,I think Ji-yoon and Ye-na play your Shaggy and Scooby as the scaredy cats of the group and their reaction to everything are hilarious,BiBi plays Daphne as the girl crush who is basically ready to beat everyone up ,while JaeJae plays Velma with her deductions leading the group through difficult puzzles and shocks you with how smart she is and that leaves Do-yeon playing Fred,although she's not the leader,her role seems to do her main job of being hilarious and the comic relief but also bringing the group together but at the same I think Ji-yoon is more so fit for this one since she leads the club and commands them really well so you could switch Do-yeon and her but when they all come together,you truly feel like your watching these high school kids getting themselves into something bigger than they could've imagined.All this is a long winded way of saying please give it a chance as it will definetly brighten up your day and is very bingeable.
