This emoji expresses the intense feeling of a heart beating as if it's about to burst from love. It's also used when you see someone so attractive that your heart skips a beat, similar to the Korean slang "simkung."

This emoji can depict a rapidly beating heart not just for feelings of love, but in any tense or exciting situation. It's useful for vividly conveying emotions in various contexts, like waiting for important test results or watching a scary movie.
