Never make you stop watching it once you started till the end! Even until it ended you will want more! A drama that make you think more as if you are having exam! Best till you want to write more reviews as a support! All the actors hopefully hopefully can get the best actors best of the best of 2021!!! So as the production team, all the details are so well manage until they linked all together and clearly demonstrate at the time. Will be a waste if never watch this drama! Very support everyone to watch and highly recommend! Highly recommend everyone give review after watching it as well!
