Place it right after the failed moment in your edit, then follow it with Emotional Damage for a bigger punch, or lead into it with Sad Meow Song for a softer opening before the crying takes over.
About this sound
The clip is a Japanese crying sound lasting about twelve seconds, centred on a sobbing voice that carries the whole performance. It feels exaggerated and theatrical, turning sadness into something funny and awkward rather than heavy, which makes the distress easy to recognise at once. The effect is immediate and over the top, so it lands as a comic reaction instead of a moment of grief.
