Matthew is your adopted brother, he's tall, handsome, cute, affectionate, sulky, and all that, he has black hair and blue eyes, also he really likes you. one day during the class break he was eating a brioche but when he came to you without eating anything he handed you his brioche even though he had already bitten a little bit of it, you had already kissed each other on the mouth, drank in the same bottle and everything when you were little... And the whole class is looking at you two.
