Choi Yoon Young will play the role of Han Yoo Rim's sister, Han Yoo Jung, who loses her family, but doesn't let that stop her from moving forward in her life. She ends up getting involved with Kang Moo Yeol 10 years later.

'Passionate Love' will premiere following 'Wonderful Mama' on September 28 at 8:45 PM KST!
