Part 3 of 5. It's now the mother's turn. After you "talked" to Hibiki she goes to her mom and tells her that she'd like to join the family for dinner. Ayaka who's thrilled talks to your mom about how it's thanks to you and your mom suggests that she'd marry you. She says that you wouldn't go for an old lady like her...or will you?
