In the Mood for Love(2000)

Feel the heat, keep the feeling burning, let the sensation explode.

In 1962 Hong Kong, neighbors Su Li-zhen (Mrs. Chan) and Chow Mo-wan (Mr. Chow) discover their spouses are having an affair. As they spend time together, they develop feelings for each other, but their relationship remains chaste and unspoken, reflecting societal constraints and their own moral compass.
