Julien Kang and Yoon Se Ah revealed that they contact each other off the set of 'We Got Married 4'.

On the January 26th episode, Julien Kang prepared a special birthday surprise for his on-screen wife. He personally made a snow man with candles on top. Yoon Se Ah commented gloomily, "I'm sorry I'm so old."

The actress went on, "Shoulders, I want you to be more affectionate. You're too stoic. Have you ever thought about me when we're not filming ['We Got Married']?" Julien answered, "I do think of you, especially when I'm eating. When it's cold, I worry about you because you might be filming outside."

He then added, "Why didn't you respond to my text message last time?" She answered, "When did I not respond?" Shoulders promised, "To be honest, there was one time you didn't. I'll express myself more from now on."

Later on, the couple celebrated at a club in Itaewon, where Yoon Se Ah surprised her husband with her dance skills.
