Sanghyun's video of the challenge to balance a water bottle on Ssinlong's abs, uploaded to the AlphaDriveOne account!

I don't know why Xinlong is doing that on top of the abs, but

Sanghyeon, who keeps challenging, and Ssinlong, who quietly accepts his younger brother's challenge, are both so cute haha.
