Place it at the end of a reaction beat, just after the stare is shown, so the line answers the moment directly. Follow it with Awkward Moment to stretch the reaction, or open with Anime Ahh before the stare for a sharper contrast.
关于此声音
This is a short Thai voice line in which a speaker asks, with a mix of curiosity and mild challenge, why someone keeps looking at them. The direct question lands as playful and slightly awkward, turning an uncomfortable stare into a light confrontation. It works best as a quick spoken reaction, turning a silent stare into a direct question that makes the listener smile while backing off.
