AA (Double A)�had a special surprise for all their fans.

The boys made their return with "Come Back" last week, and they had a special present for the fans who came to 'Inkigayo' to cheer them on. They wrote letters to their fans, writing each fan's name and attaching a little snack along with it.

The AA members took photos of themselves writing the letters on their Twitter with the message, "We prepared a small present for the W that are coming to watch us today? See you soon~:)."

The present delighted their fans, who uploaded snapshots of the gifts onto their own SNS accounts.

Such sweet fan service! Which idol or group do you dream of getting a gift from?
