This sound became widely recognized online through short-form video edits using the lyric "kimi no toriko ni natte shimaeba kitto" from the Japanese pop song "Suki Dakara" by Yuika. The track spread across TikTok and similar platforms in the early 2020s, especially in romance edits, anime fandom clips and soft aesthetic posts. Its popularity comes from how quickly the chorus sets a tender, infatuated mood, making even a few seconds of audio enough to signal a sweet or dreamy moment.
