Upon receiving many well-wishes and letters for her birthday, SISTAR's Bora thanked everyone who made her very special day even more special.

"Ack. My birthday just passed by like whoosh~," she posted to Twitter earlier. "Thank you so much to everyone who congratulated me. I read all of the letters I got yesterday. SISTAR19 is making a comeback~ please support us! Thank you and I love you. Style"

Even though she's now a year older, if the picture she posted is any indication, she seems to be getting even younger! Hope Bora had a very happy birthday!
