Mystery, Thriller, Time Travel, Detective Vibes ?
Wow, this drama completely exceeded my expectations! I clicked on it just because of the time travel theme I’m a total into those stories but it turned out to be such a well made short drama.The ML, university professor Liang Si Mu, plays more of a detective type role he travels back in time to uncover the truth behind his sister’s tragic death.
The ML and his team created a code meant for time travel, but it’s still incomplete and needs more research.😊 As the story goes on, we see more ways the code can be used for traveling back in time , making each episode even more exciting to watch.💯
The suspense and mystery kept me hooked the whole time, and they didn’t waste a single second of screen time.
The boyfriend character? Absolutely terrifying 😭 crazy, delusional, and gave me chills every time he appeared.
The entire cast delivered phenomenal performances despite the short runtime.
If you love mystery, thriller, time travel, and detective investigation themes, this is a must watch and it gets straight to the point with a clear and satisfying ending (which is a big deal for me lol 👍).
Overall, a short but phenomenal drama that wraps everything up perfectly. Highly recommended!

Not Convincing
Despite the glamorous setup and everything seemingly in place, it's just not convincing. Acting is flat story is somewhat predectable.The main lead is time-traveling to the past and interacting with people, yet it doesn’t affect the present timeline at all which feels odd and inconsistent.It would have been better if only his soul traveled back in time, merely witnessing the events unfold without being able to interfere. Also, while the main lead is traveling to the past, it felt like someone might be coming from the past too especially during that phone incident .
Overall, it's just not convincing. I'm dropping it.
