Blonde girl in Santa outfit blushing hard

This anime girl has long blonde hair in pigtails and big green eyes. She’s wearing a red and white Santa-style outfit with a fluffy white hood. Her cheeks are bright red, and she’s sweating a tiny bit. Her expression is super flustered — like she’s caught off guard or shy. She’s looking straight ahead, maybe at someone, and her mouth is slightly parted. The background is blurry but looks like a doorway or window with some light coming through. The whole vibe is sweet and awkward, like she’s about to say something but can’t quite get her words out.
