Yoon Sang Hyun is returning to dramaland with a drama about a bad-tempered woman.

In the upcoming drama "Bad-Tempered Grown-Ups," the actor will play Nam Jung Gi, a marketing department manager, who is much too nice to people. He is so nice that his colleagues jokingly call him "the walking UNICEF" after the charity, or "Father Theresa," after the nun Mother Teresa. Nam Jung Gi is unable to get mad at anyone. And this makes his co-worker, the bad-tempered Ok Da Jung, played by Lee Yo Won, even more irritable.

Ok Da Jung is so bad-tempered that her co-workers call her "Fire Da Jung" because of her fiery temper.

Will Ok Da Jung succeed in making Nam Jung Gi angry? Or will he succeed in improving her temper? That's the main premise of the drama's plot. Yoon said he was attracted to the story because of its warmth. And he feels the character Nam Jung Gi has a lot to say to people.

Yoon has played some "nice" characters before. He was a nice attorney, who had a crush on Lee Bo Young in "I Hear Your Voice" but his character lost her to the high school student, played by Lee Jong Suk. And he's had experience dealing with bad-tempered female characters in dramas. He played personal butler to the bad-tempered spoiled heiress played by Yoon Eun Hye in "Take Care of the Young Lady."

Yoon's last drama role was in the 2014 thriller "Gap Dong," although he also had cameos in the dramas "Pinocchio" and "The Time We Were Not In Love, 7,000 Days." In 2015 he took a break from acting to spend time with his new family, his wife, singer MayBee and their daughter, born on December 4, 2015. Yoon Sang Hyun and MayBee married in February of 2015.
