>>57544663We don't know. People say the first off-collab where mori made a dumb sex joke about gura, and it seems likely, but we don't know for sure.
They just have never really collabed since, aside from mandatory group collabs. Even then, it's awkward.
I dont think theres any malice between them, because Mori occasionally says something cute about Gura.
But they definitely arent close "friends" either.
As a deadbeat I hope they can have fun together again some day, but there's no indication of it happening any time soon.
