Great explanatory on the time loop concept but that's due to it having access to the original material that this drama was based on. The cinematography itself is somewhat uneventful, even the sound design felt very lacking throughout the whole drama. Fortunately the quality acting performances by the main leads were able to make the scenes feel very believable and saved the drama from becoming a failure. At least the ending is still satisfying if you're able to follow the loop and make a sense out of it.
