just poking my nose in here like the nose-y person I am to say:

It's actually my priority to end things before there could be a love triangle between the three of them. Some of the seed for that has already been planted thanks to various talks with Ren, and seeing how much Yukine was hurting during the purification ceremony (from how deeply he wanted things he couldn't have) so if she gets the inkling that what she's doing is hurting him (which is... idk, I mean, it depends on him mostly, but she's super perceptive about that kind of thing, so it could be as soon as their next thread or two??), she'll probably try to cut it off as gently as possible. Either that or it will happen via shards. It might take some time for her IC feelings to fade but with shard regain that shouldn't really be all that long.

OOCLY, I don't want there to be any danger of triangles either because that would make things too problematic for all three of them and trying to repair the... not-quite-broken-but-sort-of-mangled-and-dilapidated bridges. I would also like to see Relya grow because holy squidoodles they are cute together. So. I'll be out of your hair just as soon as feasibly possible!!!

you'll never keep her from trashlyfe tho
