KARA's Hara penned a special, handwritten letter to Kamilias celebrating the New Year and her birthday.

"Hello! This is Hara ??," she began. "It's been a while since I've actually written a letter with a pen."

"Happy new year! The weather is very cold, make sure to eat warm things and stay healthy!!" she continued.�"We're all taking care of ourselves and eating well so you don't have to worry too much about us. We're really strong you know ??"

She went on to thank fans for celebrating her birthday, and promising to grow more mature in the future. "2013 has dawned, so I'll make sure to work harder and never let you guys down."
