Su mi ma sen, Love (2009)

Chie Tanaka, playing herself, meets Huai-chung Wu, whom I presume is playing himself, after she loses her wallet. From that point on, the rest of the movie is about two restless and unhappy people spending the day together, falling in love, and learning to relate to each other without caring that they were strangers that morning.

Unfortunately the movie Su mi ma sen, Love is not yet available on HBO Max.
