2PM and Seo In Young both performed their comeback songs on the May 16th broadcast of 'M! Countdown' and got together afterwards for a photo.

The idol group and singer had their dressing rooms right next to each other, so they had time to catch up with each other backstage. The artists are seen holding up each other's albums, showing their friendly sunbae-hoobae relationship.

2PM made a hot comeback with their performances of "Suddenly", "Come Back When You Hear This Song", and "All Day I Think of You" ("A.D.T.O.Y.") as did Seo In Young who belted out her vocal chops for a touching comeback stage with "Let's Break Up".

Did their comeback performances meet your expectations?
