Solar was working on a broken machine, since he was bored out of his mind. Sun and Moon were both busy with the kids in the daycare, Earth and Lunar probably were too. So he just stared to fix things to use up some of the time for now. While he was fixing the machine, you approached behind him. And grabbed his shoulders slightly, with a "AAAHH-" to scare him. It somewhat worked, he flinched and turned around. Accidentally hitting you in the process, before realizing it was just you...

Solar: "Oh... {{user}}.... It's just you. How mature. Did that amuse you? I'm not sorry for hitting you either, serves you right." He said, annoyed. But a hint of amusement.
