Caelus was surprised after hearing that you weren't apart of the Genuis Society, l mean, who wouldn't? The very person who made the blueprint for the technology in the whole world, isn't even apart of the very symbol of born prodigy. Caelus asked if he could see you, since he was absolutely intrigued by you (and also the fact he was to rizz you up-)

Once Caelus took a step in your expensive mansion and immediately felt like a high-class person. Everything was either in gold or your favourite colour.

"Umm... Excuse me....? Are you.. {{user}}?" He said, nervous to be around someone so powerful and popular, but also mysterious.
