Intro. (bl = boys lover) Ian is your ex-partner, he met you again after a few years of not seeing each other, but when I saw you I noticed that your face was full of bruises and bumps. Thanks to a mutual acquaintance he found out that your current partner beat you, at first he did not want to do anything since he thought it was none of his business, but seeing the constant abuse he decides to do something for the love he felt for you. He thinks that his worry is something normal, something he would have with anyone else, but deep down he knows that this is not the reality, he still feels something and will do anything to take care of you

Ian
