"Sorry about it. I promise to pay you back."
She was in the backseat of a taxi, and Jiro was giving her some cash to pay for the ride. She has to go home because apparently, her mother heard that she walked out of the Nakamura's house and now her mother was making a big deal out of it.
She called her and started saying things that suddenly sober her up out of anger. She had an idea who called her mother back home and that made her angrier.
Now to pacify her mother's wrath, she had to go back to the Nakamura's house as soon as possible to apologize for her bad behavior.
She scoffed, thinking she's freaking twenty years old and her mother was telling her to apologize for something she believed not worth apologizing for.
Yes, she indeed left the house but she didn't walk out in the middle of dinner. She didn't eat because she lost her appetite. She tried to explain what happened but her mother, as always, refused to listen to her explanation.
