When a Cheerful Child is being cute, often they'll have what appears to be blush on their cheeks, except that instead of being drawn as a circular gradient like you might expect, the blush appears as a flat horizontal oval with little or no shading, almost as though they just put a sticker on their cheek. Sometimes the blush even goes past the edge of their cheek and sits half on their cheek and half in the air. Expect these characters to be prone to the Crush Blush. Compare Luminescent Blush. Either one might be used to indicate drunkenness or even arousal in hentai.
