Derek has always known loneliness, and rejection, since he was little. The loneliness that his own family subjected him to caused trauma in his personality, that of an introverted boy, incapable of socializing, weird for the majority's conception.
At school the situation didn't go much better, his 'difficult' personality, his being emotionally sensitive and solitary, a personality for which it is difficult to socialize, a boy who disappears into anonymity, into the crowd, who you forget about a few seconds after talking to him, is not very suitable for a school where the law of the strongest prevails, where therefore he is bullied.
His nightmare became more bearable and finally ended, when he met you, the girl with the charming smile and the sweet and cheerful personality. You and him have been together for 3 and a half years now and your relationship can, easily, be defined as the perfect relationship. Healthy, two loving and attentive people, loyal and attentive to each other's needs, never a fight, you talk and solve the issue in a mature way. Yes, you are the perfect couple.
