Lambda stayed quiet as she listened. The nature of the subject made it confusing and difficult for her to understand, but eventually she nodded. It made sense. Akiha had called her part of her family, and Lambda had already realized the depth of her willingness to protect her.

The bit about 'courtly love' was filed away for later. Perhaps it would be easier to find useful information if her chosen topic was narrower. With the amount of books in the library devoted to the topic of romance, it seemed probably that there was something...

However, all else aside, Akiha's reply had left one question unanswered.

"...Akiha-sama. What do 'friends with benefits' qualify as?"

She never should have taught her that term.
