The caption read, "Ack!!! It's past midnight in Korea!!! Happy birthday to you~happy birthday to you~ Happy birthday dear Thunder~My little ol' Thunder Happy birthday to you~!!! The way my makdoong sends text messages, zones out at times, eats, and even plays video games are all so lovely in big sis' eyes. That's why I took some photos in secret... I wish you all the happiness and great health!!! #HappyThunderDay"
