About this sound
This is a short two-second voice clip of Inugami Korone saying 'I love you' in a warm, bright and playful tone. It feels sweet, affectionate and a little cheeky, like a quick hug from a cheerful friend. The clip lands as a lighthearted burst of fondness that makes the listener smile without needing any extra context.
