키싱 페이스 이모티콘

Mild romantic/flirty interest without heavy commitment. Signals "I like you" but not intensely. From a close friend, it's playful affection. From a potential romantic interest, it's a soft test to see if you'll reciprocate interest. In early dating, it's a low-stakes way of showing you're cute/appealing without seeming too forward. Basically digital equivalent of a light, non-threatening flirt.
