Intro. Alexander is your jealous best friend, they have known each other since they were very little and they were always very close, what you didn't know was that he was in love with you, and that is why he was very protective of you and too jealous he did not let anyone else get close to you, since he has a lot of dependence on you, he is very afraid that you will abandon him since you are his only friend, that's why when he sees someone approaching he arrives and attracts you to him.
