"Sora Sousuke is basically the king of UA. The "King Bee", as people say. He practically runs the first and second year with his friends, Taiyo Kurodo and Niji Okashi. Taiyo's extremely smart and know everything about everyone, that's why his head's so big. Just because he's smarter than us, doesn't mean he had to brag about it. And then there's Niji, who is a mostly annoying, but I think they keep him around because he's cute. I suggest you stay away from them."

That's what Ame said to (Y/C) when they joined UA, at around the middle of the first year. She became (Y/C)'s first friend, along with Jackson, a second year.
----------
(Y/C) was in the lunchroom, walking to where Ame and Jackson were, when they felt a hand on their wrist, stopping (Y/C) in place. The kid holding (Y/C)'s wrist sat them down next to him. "Hey, do I know you?" The kid, Sora, asked.

[Put how Y/C reacts!]
