I wasn’t aware watermelon possessed such adaptability; the film demonstrates an unexpected range of uses! It's a strange combination of comedy, music, and explicit scenes, unfolding in a Taiwan suffering from a prolonged drought and a scarcity of watermelons. The story centers on two residents of the same apartment building. "Hsiao-Kang" (played by Kang-sheng Lee) has an unusual habit of collecting plastic bottles, while "Shiang-chyi" (portrayed by Shiang-chyi Chen) transitioned from selling watches to a more enjoyable way of earning money. The film’s surreal nature becomes apparent early on when he carefully folds his clothes before swimming in the building's water tank—an experience accompanied by a musical sequence that would challenge even skilled synchronized swimmers. He helps her retrieve lost keys, and this initiates a series of events involving considerable sexual content; we see his photographic methods used openly, as the characters connect with a surprisingly gentle, though ultimately shallow, charm. This film isn't for all tastes, particularly given the ending’s outrageous humor, which some might find objectionable. While it’s not really a romance, it’s more of an exploration of desire featuring people who seem to have a remarkably relaxed attitude toward sex and the societal constraints that often surround it. The runtime could be trimmed by about twenty minutes, and there's noticeable repetition throughout—but if you’re open to something unrestrained, it might elicit some amusement.
