Law is taking full advantage of Kid's willingness to shower him with affection. He isn't used to it, and it was very unsettling and uncomfortable at first, but it has grown on him. He loves feeling Kid's arms around him, wrapping his arms around his neck or waist, kissing him, the way his mate pets his hair. Killer seems a little uncomfortable with the way they're wrapped around each other, but Law can't bring himself to care. He's in his happy place, and he's not going to let anything ruin it for him, because he knows it can't last.
