The visit to the Andoram residence did not go well. On the one hand, Felicia was upset and angry that the events in that place had caused her to meet with the Biverlay family's eldest son and was mad that her father could be related to this matter. But on the other hand, Felicia was also relieved that she no longer had to pretend to be friends with other nobles.
Allen's presence in Felicia's life undoubtedly negatively influenced her nobility. But for Rachel, Allen was the one who relieved Felicia's stress and gradually made Felicia more open.
Everything was for Felicia's happiness. So she had to stay close to her.
That's why, right now, Rachel is confused and worried because she won't be with Felicia for a while. After all, Felicia went to the dungeon to gain more experience.
