While wearing matching white button-down shirts the members took silly pictures of themselves looking cheerful. In the first picture Jaejoong tweeted "Hey Junsu ha" while Junsu has positioned himself as though he's about to bite fellow member Jaejoong's neck while Yoochun grins so widely that his natural eye-smile appears.
The next photo Jaejoong shared with the caption "He came up all of a sudden and said 'Hyung, let's take a selca(Self-camera)!' and it turned out like this" shows himself and Yoochun making playful faces.
Fans were delighted to see the JYJ members looking so happy.
