Rookie female duo 15& teamed up with nine members of Hanbit Performing Arts Company's Light Sound, a visually impaired choir group.

A staff member revealed the above picture as he tweeted, "15& Ji Min and Ye Rin who visited our studio and the Light Sound children. The song is really daebak!!" The staff also thanked 15& by adding, "You guys worked hard filming, recording, and caring for the children."

Park Ji Min replied with, "Thank you for recording our song well. It was a fun time with the dongsangs." Baek Ye Rin also commented, "It was a meaningful time. It was really fun."

Park Ji Min and Baek Ye Rin stood together with nine choir members dressed in a preppy skirt and shirts. The pair looked like they were having a good time as they held hands with rest of the members.

Meanwhile, as reported earlier, Park Ji Min  donated 50 million won (~$45,000 USD) to the Hanbit Performing Arts Company from the winning prize money she received from SBS' 'K-Pop Star.'
