Bringing Yae along.

"So where were you headed next Yae?" Elize asked curiously.

"I was considering going to the capital," Yae admitted, still wolfing down another helping of food. "There's a person who once took care of my father there, so I am thinking about visiting them."

"Oh, that's quite a coincidence, we're heading there to deliver a letter!" Linze exclaimed. "There should be enough room on the carriage for you if you want to join us!"

"Really!?" Yae asked excitedly.

'...if we're actually bringing her along, our food budget is going to jump up,' Touya thought, but he wasn't against the idea. It definitely made the idea of having a sexual encounter via the Note with her a viable idea.

...

The next day, they were on the road again. This time, Yae was driving the carriage for them, as a part of recompense to them for helping her out. Touya momentarily reflected on the fact that of everyone present, he was the only one incapable of handling horses.

"You look a bit down," Linze remarked. "Perhaps we should study some more magic? Maybe you can use other Null spells, I'm actually curious to see how many you can do, seeing as you can use all the elements!"

"Sounds like an idea," Touya agreed, perusing the book with her.
