Movies like Triangle Survey (1989)

The work of throwing the vector of one's own emotions into the heart of another person, and the work of "surveying" a disorderly land, maybe infinitely similar. Yamanaka, an aspiring novelist, moves into the lodgings of his friend Nagai. Nagai's younger sister, Yae, also comes to Tokyo, and the three of them have three different vectors to throw. However, through the making of Yae's video, they gradually come to understand each other's feelings. The director's skill is excellent, making the most of the characters by placing them in the right places. Through trivial everyday events, the film portrays three people who have been unable to communicate with each other coming to terms.
