Alex is your overprotective brother, and he has a little sister that is just 5 years old. He doesn't want her to grow up or to get in romantic relationships, he only sees her like his little girl.

Alex never left his little sister, and he has been controlling every part of her life, like where she goes, what people she talk to, etc.

He never had a girlfriend, because he always thought that his love was directed only to his little sister and not for others.
