Heartbeat sounds have long been used in film and online video to signal fear, excitement and romantic tension, because the rhythm is instantly understood without any words. In short-form edits, especially Gacha-style character videos, a fast heartbeat is often layered under emotional scenes to show what a character feels but cannot say. The Thai title translates to a strongly beating heart, which matches that use perfectly. Its short length makes it easy to drop into a single scene, and its simple, physical sound keeps it useful long after trends change.
