Place this clip after the unanswered message in your edit, then follow it with the Bruh Soundboard Button once the lack of a reply has registered, and keep any other reaction sound for after that second beat so the sequence stays focused on the ignored plea.
关于此声音
This is an 8.7-second voice clip built around the Portuguese phrase alguém fala comigo, meaning someone talk to me. The line is a direct plea for a reply rather than a conversation starter, and hearing it on its own gives the silence around it an awkward, lonely feeling that listeners recognise from being left without an answer.
