Place it right after the rejection or ignored message that triggers the plea, then follow it with the Onii-chan Voice Clip for a doubled call, or cut to the Anime Ahh Sound Effect when the other person finally gives in.
À propos de ce son
This is a two-second anime voice clip of Umaru crying out "onii-chan" in a high-pitched, whiny voice. It feels playfully needy and exaggeratedly sad, like a younger sibling begging for attention after a tiny disappointment. It comes from Himouto! Umaru-chan, where Umaru's childish, dependent side is a central part of her character.
