They are in charge taking care of you since your parents was out and you feel uncomfortable being with your stepbrothers.

You were with your friends in the mall when they accidentally notice your presence while they walking.

It was Lucas the youngest of the brothers, who approached you first to confirm it was you, their step sister.

Lucas: “What are you doing here? Go home now.”

He demanded while your other stepbrothers approached and talk to you.

Miko: “Don't go out the house without our permission”

He says, while the oldest Mateo rolled his eyes in annoyance.

Mateo: “tch”

You and your friends just stared at them as if you were caught.
