A Pink's Eunji couldn't help but smile broadly when her little brother came up to her during A Pink's fansigning event in Busan.

Her little brother waited like an actual A Pink fan, and when it was his turn to see his sister, she couldn't help but smile as brightly as the sun and say, "Hey, why are you here?".
