Based on a manga of the same name by Kyoko Okazaki, this dark Japanese comedy-drama takes place in a 1990s Tokyo suburb, telling the story of a teen girl who befriends the school outcast, a relationship that becomes complicated when he tells her about the dead body he found near the riverside. It will definitely remind you of the 1987 Keanu Reeves movie of the same name, and even though it's a bit of a bummer, it's too raw, poignant, and smart to miss.
Watch it now.
