Euphoria

A man kills her lover. She watches him clean up, reminding him to use special garbage bags to avoid a fine from the building management; she helps dispose of the body, yet feels like the murderer herself. Was it her lust, or the man's pride that killed him? Or did she kill his pride? She doesn't understand why things turned out this way, thinking this time would be different, but the result is the same...This unsolvable mystery is like a wave, crashing over her again and again, and she can only open herself up and use her body to endure it.
