Plan Korea recently chose K-pop girl group Girl's Day member Sojin and Hyeri as their ambassadors. The girls uploaded their fun photos on their Twitter account to show and support the advocacy of Plan Korea to help children around the world.

Sojin posted her message saying, "Today will be our most proud day after debuting. After returning from Thailand next week, I'll probably be very proud of myself after that? I'm thankful for today. 'Plan Korea' fighting. FlyFly~."

Sojin also posted an adorable photo alongside Hyeri making a heart sign for their fans. Fans who saw their photos commented, "I'm so proud of you guys," "You have pretty hearts too," and "It's good to see that you guys are volunteering your time even in the middle of your busy schedule."

Girl's Day is said to be working with 'Raise Your Hand' and 'Because I'm a Girl' to give their support and reach girls all over the world.
