Place it at the end of a failed-moment edit, after the action has finished and the reaction shot begins, so it carries the closing beat. Follow it with Emotional Damage Meme Sound for a sharper punch, or lead into it from Sad Meow Song to build the closing moment in two steps.
About this sound
This clip is a slow, drawn-out Mandarin vocal line lasting about ten seconds, sung with grand, heartfelt sincerity over a gentle melody. It feels melodramatic and lonely, like a scene meant to be tragic, which makes it funny when placed over ordinary or awkward footage. It comes from Yi Jian Mei, performed by Fei Yu-ching, and spread widely in 2020 as an ironic meme cue.
