This drama is a mix of a few genres/vibes. Mystery aspect (the female lead is trying to figure out her world/the time travel stuff and the male lead is looking for his lost friend). Everyday life aspect (a big part of the drama is seeing the female lead working as a hairdresser/make-up artist and her struggles at work). Romance (more as a sub-plot but definitely there, the romance is darker and NOT a rom-com). Because of all the things mentioned above, the drama alternates every few episodes between very light and fun vibes and very dark and angsty vibes.

The drama tells the story of the female lead who has a car crash and believes she has travelled to a parallel universe and at the same time has jumped from 2025 to 2018. She meets the male lead who knows her parallel self and together they try to figure out the mystery of who the female lead is and how she ended up in 2018.

POSITIVE:
- Several fantastic plot twists.
- Hot chemistry between the leads. I could always feel the intense love and angst between them.
- No plot holes. All mystery questions are all answered in the end and make sense.
- Suspense aspect is done well as I was always at the edge of my seat.
- Mystery aspect is done well as the story keeps you guessing what’s real and what’s not.
- Strong-willed female lead. She was abused, yelled at constantly for no reason and yet she stood firm and strong. Her character development was amazing (seeing her being anti-social to making long-lasting friendships).
- Cinematography is stunning, especially during rain and snow scenes.
- Acting is top-notch especially from the female lead.
- Happy ending that is wrapped up well.
- The portrayal of mind distortions are done well, especially when the female lead is losing her mind and seeing things.
- Hairdressing/make-up scenes were cool to watch as it was unusual to see in a cdrama.

NEGATIVE:
- Last few episodes focused too much on the female lead’s career and a particular side character which made the drama a little boring and draggy.
- Needed more cute romance. Only one fake kiss scene (which I can get past that) but I wish we had seen the main leads hug more and have more cute scenes together when they were a couple.
- In episode 7 the male lead is manhandling the female lead. I personally didn’t mind it because it’s fiction not reality but if you are sensitive to these things, it might be best if you skip this drama.

OVERALL:
If you are looking for a drama that has mystery, career/life struggles, mental health issues, darker romance and cool plot twists, watch this drama.
