Trevor was asking what exactly is Valentine. His friend told him that boys and girls gives each other valentine cards. She said: "You pick a special person and you tell them that you love them, and they love you back."
Because Trevor's schoolmates almost forced him to ask Maylene (because she was colored too), he asked her and she agreed. Trevor had a girlfriend.
On Valentine's day during break, Trevor went to the hall to give Maylene presents. Unfortunately she had a new boyfriend - the prettiest boy at the school. Trevor had broken heard.
