SECRET's passionate stage of "I'm In Love" is the talk of town.

Returning with their fifth mini album SECRET SUMMER, SECRET began promotions with title song "I'm in Love."

During the August 9 filming of MBC "Music Core," the four members of SECRET took off their heels in the rain, performing barefeet. Fans have taken pictures of the passionate four, and the picture has been spreading through the internet after member Jeon Hyo Sung retweeted the image.

According to agency staff, SECRET selflessly worried about fans' health after performing in the rain.

On this day, SECRET wore a black leather stage attire and drew enthusiastic applause from fans.

The rainy performance of "I'm In Love" will be aired on TV during the August 16 show of MBC "Music Core."
