She also shared BTS photos of her riding on the back of a motorcycle, giving a sneak peek of the high school love story she will act out.

As mentioned previously, main leads Sung Hoon and Choi Yoon Young will play star-crossed lovers. Sung Hoon will play the role of Kang Moo Yeol who seems to have it all on the outside, but grows up with family issues and pain from the loss of his former love Han Yoo Rim (played by Girls' Generation's Seohyun). 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!
