To celebrate the Christmas holiday, the idol couple headed to the slopes and snow. It was Na-Eun's first time skiing, and though she leaned on Taemin a lot, he was a beginner too. He said during his solo interview, "Today was my third time skiing. I taught myself how to ski. Instead of skiing, it was more like dating."

Still, he tried to teach her what he could, starting with how to get on the ski lift. At one point Na-Eun stated she was cold and Taemin tried to warm her up with his gloves and a hug. Judging from their wide smiles, they had a lot of fun.
