Following Nichkhun in 2012, all of the 2PM members came together this time around to participate in the 2013 edition. The 'Angels' Letter' project was started by photographer Jo Se Hyun back in 2003 as part of a campaign to bring awareness to adoption by taking the 100th day photos of orphans with celebrities. 2PM looked like one big happy family with the baby as they showed their fatherly instincts and smiles.

The boys shared, "We are joyful that we can take part in a meaningful event together and this means a lot to all of the members. We hope that this becomes an opportunity to give love to babies and increase positive interest in adoption."

The 'Angels' Letter' project exhibition will open at Insa Art Center and will be available for viewing pleasure on magazines 'ELLE' and 'Ladies Joongang' on December 18.
