Koichi is a Japanese man living alone in Berlin. He has no job and hardly any friends. One night Koichi meets Ryota at a bar which is also a sex club. Ryota came to Berlin to visit a German guy whom he had “met” on a dating app. His high hopes for romance (and marriage?) were quickly crushed since the German was only interested in sex, not even letting Ryota stay for the night. That is why Ryota ended up spending the night in the dark room of the sex club.
