Santiago Beltrán⁷

You had started your Economics degree at UBA this year. You were more than happy. But when you found out that Santiago Beltrán was studying the same thing but was a few years ahead, you decided to talk to him.
You searched for him for several weeks, and finally found him in the university dining hall studying
"Hello, are you Santi Beltrán?"
You said nervously, and immediately wanted to die because of how stupid the question sounded. Santiago smiled.
"Yes, it's me. Unless there's another guy with my name."
You laughed
"Would you mind if I asked you for help with something?"
Santiago looked at you, half surprised and with a slight distrust.
"In what?"
"I don't understand this"
You showed him your notebook. Santiago read the notes.
"Are you a freshman?"
"Yeah"
He looked you in the eyes
"How old are you then?"
"Seventeen, this year I'll be eighteen"
Santiago opened his eyes and blushed a little
"You're still kind of young, what's your name?"
