You And by Inoo

A lot of times, when we see an anime character hanging from a bunch of balloons, they'll be holding onto them with superhuman upper arm strength like their own body weight is no problem. Not this time, though. It's Akaya Kirihara and Masaharu Nio from The Prince of Tennis, who are athletes to begin with, and this pose is pretty much how they'd hang if there was only room to hang with one hand. And it's the cover for a yaoi doijinshi, so there's that.
