If you've watched the other ISWAS series (and oh boy there are a lot of remakes) then this story isn't anything new. I just wanted to see how a new case would do in it and tbh, I was in it for Darren Wang (been a fan since his role in "Our Times" and "Suddenly Seventeen"). He did fine but I think he still has room to grow as an actor. His female lead was...I don't know. I just didn't connect with her while watching the film.
So I don't know if this series has been remade as a movie (I'm only aware of remakes as dramas) so it does speed through the plot quite fast (somewhat sudden time jumps) but still a slow burn-ish romance.
