Group Brown Eyed Girls' Gain revealed teaser images for the age 19 and above concert, revealing her sexiness.

Brown Eyed Girls' age 19 and above concert 'Tonight 37.2°C' is coming in 2 weeks, and Gain revealed a teaser video through YouTube.

In the video, Gain comes out as if she's getting ready to go out, but in her eyes, her getting hurt from seeing her past lover with another woman is shown. Gain seems to want to be freed from these memories that tie her down.
