Find out the gangster who wants to kidnap her and kill her humanely. Correct her misconception that "I am a human trafficker". Stop her from stewing Dumbledore's Phoenix Fawkes! In order for her to go to school, I had to help her feed an entire orphanage. But she packed the food on Hogwarts plates and pestered me to open the portal to send it back every day. Emily: "Bad guy! Human trafficker! Open the door quickly, my brothers and sisters are still hungry!" Me (holding my forehead): "... It won't happen again."

She has you in her heart! I looked at the girl who was usually as shrewd as a little fox, but would stand in front of me regardless of herself when I was hurt... It's over, my only "unequal exchange" seems to have appeared.
