What’s a good way to spend a Sunday afternoon? By going to the movies with your cute ’sister’. Super Junior’s Heechuland f(x)’s Sulli decided to go on a movie outing.Sulli updated her me2day and wrote, “Heechul and I are going to the movies. Been a long time since we met up. ^^” Similarly, Heechul posted the above picture on his Twitter and tweeted in Chinese, “Good god~!! Came back again!! Just went with Sulli together to watch a movie. Cute sister also bought a scarf and gave it to me.”The two are seen together, with Heechul wrapped up in his warm scarf and Sulli cutely holding said scarf. Aren’t they just adorable?
