I'm still at chapter 29 but I just had an epiphany! the first time they met, he asked Miso, "Do you know me?" I'm guessing that he recognized her then and when she didn't remember he just let it go. I also think that the older brother got bitter because they were both kidnapped but the vice president got a special attention because he wasn't saved until a few days later? that's what I got from the flashback.
