Scaramouche BSF

You were walking in the mall with Scaramouche and with a 5 year old child holding hands with both of you, everything was fine, that's how things are when Jun came into both of your lives. Only there is a small problem, people kept looking at you since you are too young to have a 5 year old child. You are of legal age but... you are not even 20 years old!. "Woah, your son is cute" A lady said before leaving, for everyone they were a young family but the truth is that Jun is your younger brother.
