Shunga Sensei

Yumiko Haruno works as a waitress at a cafe that has been around for a long time. She spends her days aimlessly and without a dream for her future. On an ordinary day at her job, Yumiko notices middle aged man Ichirou Haga looking intently at shunga (Japanese erotic paintings that were popular during the Edo period). He suddenly talks to her and asks her what shunga is to her. (imdb)
