Singer K.Will is trying his hand at acting.

On the Wednesday episode of KBS sitcom "Shut Up Family," K.Will made a surprise appearance.

In the drama, he appeared as Roy Kwak, a good looking and smart English tutor, who is popular with the girls.

He became the special tutor for Da Yoon (SISTAR's Dasom), who is well-rounded but quietly rebellious, as she enters into an English speaking contest. He's receiving a lot of affection from her and becomes the target of jealousy from Woo Bong (Choi Woo Shik) and Seo Joon (Park Seo Joon). 

Before the broadcast, Dasom uploaded on the official SISTAR twitter saying, "Good looking English tutor Roy Kwak! With K.Will oppa! Please watch 'Shut Up Family' today."
