The only acting I liked was by the main leads and the girl pretending to be a boy in the group. The ML having a chip in his brain which has to be changed every ten years and when that happens his memories will be wiped. There wasn’t much backstory to his past except for very few flashbacks and a brief couple minutes explaining him and his father got in an accident and if the child version of ML didn’t have surgery he won’t have much mobility but with surgery would require a chip for him to function but will wipe his memories. We see tech beyond our times so there’s not much sense for it in story. Then you got an unfinished story since this premiered in 2018. No updates about finishing or scraping the drama. Being left on a 3 year cliffhanger is very irritating. Music is very mediocre in the drama and the story is disorganized. The only thing that would keep me going is to find out the managers involvement with the boy member who was hit by the car in the first episode, see the revenge and see what happens when the FL’s friend who is pretending to be the one the ML likes since his memory is wiped. We’re left with he made a tape attempting explain things. Will this drama ever be completed? I would recommend NOT to watch this until there is a confirmed part 3.
