Singer-turned-actress Nana will take on her first leading role in the upcoming SBS series “Four Men,” where she is to play a police detective.

On Monday, the show’s production company Mountain Movement Story and Victory Content released photos of Nana acting.

During a press conference for the drama last week, she expressed hope that this could be her big break as an actress, adding that she is working hard on action scenes.

“I want to do the action scenes right, so I’m preparing and learning every chance I get. ... I’m so excited that I get to present myself as a strong woman,” she said.

The show also stars Park Hae-jin. It started shooting last week.
