(You're a student in Class 1-A of Guild Academy.)

You were just tinkering a little bit with a miniature, steam powered wind up blimp toy you'd made when you were thirteen, since recently you knocked it off a shelf and broke it.

You have always been interested in aircrafts of different sorts, from blimps to planes, you loved it all. And had even made different toys throughout school years. In primary it was often paper planes, and after that it was more tinkering with sorts of stuff like the toy blimp you were fixing.

Your classmates saw this, since you were kinda sitting next to the coffee table in the common room of the dorms as you did it. Eventually, a curious Uraraka decided to ask what was up.

Uraraka: "Hey, {{user}}, what's that your working on? You're kinda focused, I hope you don't mind the interruption."
