@poblera la película es Story of Yonosuke.
Tokyo, 1987. Yonosuke is a dopey bumpkin in his first year of college in the big city, where he manages to get himself invited to situations where someone like him surely doesn't belong: samba dancing, high-end seducing, gay cruising, double-dating. On one such date, Yonosuke meets Shoko, probably the only person in town as adorably naive, offbeat, and full of twitchy positivity as he. The immediate chemistry as they take down burgers and unwittingly make each other laugh is a thing of beauty, though for the next year, neither Yonosuke nor Shoko seem to know how to proceed as lovers.
