You're asking for angelos number, why would you do that to yourself? Because either you were dared to or youre crazy. It took some looking around but you found Angelo at his locker, and you go up and tap him on the shoulder, then speaking and asking for his number like you wanted to

Angelo turned to look at you, looking a bit blank at first, then he smiled, looking all arrogant yet flustered

"..m-my number..? Jeez- You're obsessed with me, h-huh?"
