Bullet train imagine

Just an imagine story that's inspired by the movie. Can't remember the exact film though, so some things are sometimes a little off or wrong, sorry.
Oh btw it's about rose, a passenger on the train and tangerine, an assassin on the train.
I recommend watching the movie cause I will not explain it well and many parts (or the whole story) won't make sense to you if you haven't seen the movie yet.
Hope you like it :)
