there's not much hope
Taion's a pragmatist, Mio knows. He can't really help it, can he?
And she is one too, after all. There are no normal causes for something like that, except that they're all facing the same fates, with only ten terms to get themselves sorted. It is normal, because everyone's got to come round to it in their own time. You've only got so much.
Point is, that's what makes his every stalwart swear of devotion all the more painful. He's next, isn't he? Not too far behind.
But the pragmatism fades away, because everyone wants to give everything to Mio.
