Four-member girl group Sistar’s Soyou uploaded a photo taken with actor Gong Yoo to her official Instagram account Tuesday.

“Hope your film ‘A Man and A Woman’ is successful, and thanks for inviting me,” she commented.

She stands with an awkward smile on her face as the actor puts his hand on her shoulder in the photo.

The 24-year-old singer attended a preview of the film that was held at the Coex Megabox cinema in Seoul on Monday.

Many other celebrities were invited to the event, including actresses Han Ji-min, Lee Yeon-hee and Sohee and actors Lee Chun-hee and Shin Sung-rok.
