Place this clip at the point where the forgetting is revealed, then follow it with a romance sound effect for an ironic contrast, or precede it with a dun dun dun button when the edit needs the reveal to land as a plot twist.
About this sound
This is a short sung excerpt in Turkish built around the line 'duydum ki unutmuşsun,' meaning I heard that you have forgotten. Lasting about seven seconds, it carries a single melodic vocal phrase rather than speech or an effect. The feeling is wistful and heartbroken, with a dramatic ache that makes being forgotten sound grand and sorrowful.
