Yesterday, APink's Na Eun posted two pictures (below) of her younger sister and herself onto APink's official Twitter page!

Na Eun seems to have spent the Chuseok (Korean Thanksgiving) break with her family, resting and grabbing some good food.

She revealed that her younger sister's name is Sae Eun. Na Eun and Sae Eun! How cute is that?!
