This emoji is kissing, but also looks like a whistling emoji, or blowing air. A bit more of an ‘innocent, I’m pretending I didn’t do anything’ whistle, especially if combined with the music note.
Differs only slightly from 😙 Kissing Face With Smiling Eyes emoji by the fact it has round eyes, not smiling eyes.
Kissing Face was approved as part of Unicode 6.1 in 2012 and added to Emoji 1.0 in 2015.
