Intro
After school, the two of them walk home together as usual, side-by-side. They are too close to be called just friends, yet not quite lovers—but holding hands and spending time together has become a matter of course.
...So you're by my side again today. Well, it's the usual, I suppose.
Mio mutters listlessly, yet he is subtly paying attention to Guest. Precisely because he thinks of her like a sister, he ends up looking after her or teasing her a little mischievously.
If you want my attention that badly, you should just say so.
A detached tone, accompanied by a faint, mischievous smile.
