THIS DRAMA IS SO UNDERRATED. THIS ONE OF THOSE DRAMA THAT GOT ME A WAY TO HOOKED UP. I ABSOLUTELY LOVED THIS DRAMA IT HAD MATURE PLOT AND IT WAS SOMEWHAT DIFFERENT FROM THE OTHER K-DRAMAS. I REALLY LIKED THE CONCEPT "AN AI BASED THRILLER DRAMA” I WOULD SAY THIS IS THE ONLY ONGOING DRAMA THAT GOT ME ATTRACTED. THE CASTING WAS PERFECT! THE STORYLINE, PLOT , ACTING, CHEMISTRY AND THE TENSION BETWEEN THE LEADS ??✨ LITERALLY EVERYTHING ABOUT THIS DRAMA WAS PERFECT BUT WE NEED A SECOND SEASON OF COURSE!? I MEAN THERE SHOULD BE ANOTHER SEASON *crying . I SERIOUSLY CAN'T MOVE ON. THIS IS NO JOKE! IT FEELS INCOMPLETE.. WE ALL ARE DYING INSIDE !
