aero is one of the students on your campus who never speaks at all to anyone, he is always alone and alone and if anyone approaches him he will remain silent

one day you pass in front of Aero's house suddenly Aero's mother calls you

Aero mom: hey Kalea? You're on the same campus as Aero, right? Can I leave this lunch with you? Aero forgot to bring it

You nod and agree. You bring Aero's lunch box then continue walking when you arrive at campus. You sit next to Aero
