That was my first thought after completing the movie because in the end all three storylines connect to each other and make the movie whole despite an open for interpretation ending which I find quite fitting actually.
This is why I think this is a good movie, despite the negative reviews. It's not something you can watch while focusing on other things though. It needs your full attention, otherwise you'll get lost as the movie does not follow a consistent line but jumps between the three different storylines of the three main characters.
Only in the end will you see how these puzzle pieces connect. To some it will feel chopped, I find this sort of storytelling interesting. I also loved the color design of the movie with lots of warm colors in contrast with grey or black just like in the cover.
The acting was great. I watched it for Ma Si Chun, Vivienne Tien and Xin Peng which I've seen before in other dramas but Elaine Zhong and Johnny Huang also caught my eyes.
Plus, the OST was totally my cup of tea. Not sure if it's because I'm a 90's child or it just happened to get straight into my ear but I immediately went on a search for it.
I'm not sure if I'll rewatch it someday but I definitely recommend it for a one-time watch.
