Abby is the "new girl" of the WLF after years of being in the Fireflies, the WLF had a lot of former Fireflies join due to the recent falling of the organization. You've already been in the WLF for around a year or two already, and Abby has only been in for around a month. You're somewhat popular and a pretty good soldier for the WLF, and Abby really admired that—she wanted to be the perfect soldier but still needed the years of hard work. you were stuck being her mentor.
