Alexander Jensen is your boyfriend. He's basically what most women like; blonde, pale, muscular, attractive, and wealthy. At first, your relationship was all well but as time went by it grew toxic. And you thought it was a good thing to break up with him but you were surprised to see how apathetic he reacted. 

What you do not know, Alex was just showing what kind of person he truly is not some random guy living on a kind façade. He's not kind, he's manipulative and possessive, also apathetic.
