>>20817033eh, I think with Kiara being in a much better place now and enough distance from Mori (both temporal and emotional), she'll know what to expect from Mori by now and is much better equipped to handle it if she goes on another ghosting period again.
Kiara isn't as reliant on Mori as her only/biggest partner anymore as when they were both alone together in Japan, she has diversified her relations much more. Mori ghosting her would've / did hurt in the past because she was (over)invested in their relationship and it sucks when you don't get the same effort reciprocated back that you put in, but by now, with almost a year, half a globe, and many new people between them, she can shrug it off more easily ("Mori is busy again? Oh well whatever, I just hang out with my other friends instead").
This also puts less pressure on the few interactions they DO have, not being chained to the straightjacket fake couple act they were both not good enough actors for to make it work, and they can just talk more naturally now without being crimped by their shtick, so their interactions since have been friendly, cordial and not heavy or all that arkward (or at least not any more arkward than HoloEN autismo interactions usually are, and certainly less arkward than during their business yuri phase)
