1. "Ahaha..."
2. "You're right!"
3. "Yeah, (I'm not) (emotionally) ready."
4. "TWO BOKES."
5. "Akko had a boyfriend! She must have tons of experience!"
6. "I don't know! I'm the only one with no experience!"
7. "What does she mean 'not ready'!?"
8. "I need to learn about it too!"
9. "This part of page 23 contains several nuances that are hard to translate. A literal translation of the first two lines would be as follows:"
10. "Mari: Yeah, (I'm) not (emotionally) ready."
11. "Akko: Y...you're right, (we're) not ready."
12. "Because Mari doesn't actually use the words 'I'm' and 'emotionally' when talking to Akko, but just implies it, Akko thinks Mari is telling her than she's done something wrong and that they aren't ready to have sex because she's missed some kind of important step in the 'setup' (possibly meaning foreplay, etc.) Akko can't figure out what she's done wrong and thinks it's because she doesn't know the correct 'procedure' because she's never had sex before. She says 'you're right' to make it look like she knows what she's talking about by acknowledging her imagined deviations from 'proper procedure.'"
