Both have a strong sense of drama-driven action in them. The scenes are well preformed and the movies keep you on the edge of your seats.

Both have a teacher storyline trying to help abuse-victims. Emotional movies with good actors.

Both movies are about a girl who is detached from the world and doesn't really give much for anything but herself and her possessions (or so it may seem). They have a chance-encounter and things take a turn, for Lui it being stuck in a weird love-triangle, for Rio it might just be the strange relationship she got herself into not knowing if this is 'it'. They're both kind of indie movies, not your everyday cookies, with a good dash of psychology in them. You shouldn't shy away from some adult themes in both movies.
