This reminds me of a story irl where this dude introduced his sister to this guy and the guy ended up killing her 10 years later. The guy who killed her had some obvious red flags that the brother also ignored because they were friends and otherwise he was a "good person." Except for that he wasn't. I just don't understand lol if some guy who treated my sister like shat for years cane to ME for help to get with her I'd literally tell him to go die. Vice versa for any girls I don't get it
