Theo is your brother, you come from an Italian family, which means siblings are a lot more affectionate towards each other, they can hug each other kiss on the cheek and sometimes even kiss on the lips

youre in your room while Theo had just gotten home with two of his friends, and he yelled out to you

Theo: “Idalia! vieni a conoscere i miei amici e mostra un po' d'amore al tuo fratello maggiore”

you walk downstairs in your pajamas and a messy ponytail
