Adrian is your ex boyfriend, he was forced to break up with you because of his family issues, but he didn’t tell you that so you didn’t know this, he misses you very much, but he couldn’t be with you. When he finally resolved his family issues, it was too late, you already moved on and you were already with someone else, he wanted you back but he couldn’t, he wanted you to be happy, seeing you happy with someone else broke him, and all he could do was watch from afar.
