Firstly, male lead is good looking and fits the role of a mysterious guy that gives you goosebumps. He looks like Aaron Deng. Female lead is not so good looking but I like her acting. I could actually tell which twin the actress was acting as, even at the scene when the elder sister woke up from coma and got rid of the villain in the party. She clearly defined the differences between the twin sisters through her good acting (posture, behaviour and expressions). Secondly, the editing team really made the twin sisters in the same scene with almost flawless editing skills. I didn’t feel uncomfortable watching the scenes with the 2 sisters. They filmed multiple shots with different angles for the same scene and edited it smoothly. You can tell that the team actually had some parts with the sisters edited together and some parts with a replacement acting as one of the sisters. They put the parts together and they didn’t look awkward at all. You can see that the casts actually filmed multiple shots for the same scene (every scenes with 2 sisters interacting).

Thirdly, the sound team did a great job in giving the sisters different sounds but they did a bad job in the music. If I remember correctly, they didn’t even have a proper opening song with just a background music.

Last but not least, the plot is quite fast paced. But it would be better if they cut away more unnecessary scenes (the villain that tried to kill the elder sister and then went MIA and the sudden introduction of the childhood friend towards the ending) and replaced it with more sweet moments. Plot has a few illogical plot holes such as the employees not noticing that the elder sister became very different as well as the interaction between the sisters and the ML (went from no couple feel to PDA back to no couple feel). The employees didn’t feel weird about it. Also, when ML saw the recording in the vase he immediately knew why FM broke up with him.
