I feel like basically every character on this show was dumb as hell!

Not because they believe in past lives or magic, but they didn't even try actually investigate about the things that happened. For example. Hongjo cast a spell to heal Shinyu, but he never went to his doctor to check if the spell was actually working. They just accepted that his love for Hongjo is just magic, but later they found it was "meant to be", so this whole magic plot was basically meaningless. The whole plot was created to make them fall in love, but we never got any answer how they remember their past lives or if his love for her was actually real, or they just went with it.

Sadly, this was the main part of the story, so I can't give this more than 7/10, BUT overall, it's a good Kdrama with likable characters, but with lazy writing. In my opinion, the actors made this show better than it actually is.

The chemistry between Boah and Rowoon is top-notch, but their characters making the dumbest decisions every time. This is such a typical thriller/horror writing when the characters know someone is after them, yet they still don't want to call the police or remain in a safe space.

Also, the side characters, especially their co-workers were annoying, I mean, BIG TIME! The only good character was probably Shinyu's mother and his best friend.

What I didn't like is that they said, Hongjo doesn't have anyone, yet in episode 13, I think, we found it that her landlady is actually her mother's best friend? What the heck?

So, in short, I think this is a fun show, if you can forget all the mess that the writer did with the story. There's nothing special in this show, but I don't think it's a waste of time, but only because the actors did a great job!
