Amid the vast sea of mediocre cdramas, this one is a true mini gem. This drama is about the male lead who finds out his first lover committed suicide. Accidentally, he discovers he can time travel, and tries to change the past in order to save her.

Note, there is a post credits scene at the final episode that explains the time travel (I’m pretty sure it was done because of censorship).

POSITIVE:
- Mysterious and suspenseful plot.
- Lots of unexpected and cool twists and turns.
- Good balance between angsty and sweet romance.
- A true time travel story.
- Great cinematography.
- Well-written script without stupid cliches or draggy/annoying parts.

NEGATIVE:
- Some things happen a bit too conveniently but it's fantasy after all and it keeps the plot moving so it's not a big flaw.
- Ending doesn’t fully wrap up (if we don’t take into account the post credits scene). While we’re given hints about what happens, I wish it had been fully shown. I was deeply invested in the story and main leads so I would’ve liked all loose ends tied up. That’s the only reason I’m giving it a 9.5.

OVERALL:
This is one of the best mini-dramas I’ve ever seen! I was on the edge of my seat the whole time. The drama is reminiscent of The Time Traveler’s Wife (USA) and Yesterday Once More (Chinese), so if you love time travel and romance, don’t hesitate to watch it.
