Kang Shin is 17 yrs old and volunteers at the local orphange, his parents would rather see him have a paying job but are glad he keeps out of trouble. He writes to his idol cousin, Kyungsoo and is surprised when he receives a letter saying he will come for a visit. Shin eagerly awaits the arrival of his cousin but gets the shock of his life when not just Kyungsoo but all the male idols of SME hop of the bus with suitcases in tow. 

After causing a ruckus, a desperate Soo Man send his idols to help at the orphange in an attempt to clean up their act and give them a better image in the eyes of the public. Shin's co-workers are thrilled to have idol volunteers but all he sees is fake smiles and stuck up personalities. How will daily life go at the orphange with the idols?
