On February 22nd, Rainbow's Woori celebrated her 24th birthday in the middle of a street. Because of the girls' busy schedule (with a recording for MBC's "Bouquet" and several late night college events), they found time to celebrate after 10:00 PM. Returning to Seoul, the girls realized what time it was and afraid that they were going to miss Woori's birthday completely, they decided to go ahead with the party right there in the middle of the street. With their pre-prepared cake in tow, they gave Woori a surprise, and had an unforgettable impromptu party. Woori commented, "I thought we wouldn't be able to celebrate because of our busy schedule, so I was very thankful for the members' care. Having my party outside in the middle of a street was both unique and fun." After completing their "A" and "Mach" promotions last year, the girls have been busy attending college events, which has now earned them the honor of being the #1 most invited celebrity guest.
