>>108962160Sunny and Mogu (Vivi and Kunai) ended up doing stuff together after leaving, but dunno if they still do things regularly.
Mint and Mogu are friends and chat about brainrot, but they haven't done much together content-wise.
Sunny and Sayu actually played some games together and bonded over hagdom.
I know Matara's still close with Mint, and Matara's also close with Miki, but idk if Mint and Miki have reconnected properly yet, or if they ever will.
U-san's friendly with Doki and notFulgur and have done stuff together.
Doki ended up playing with Sunny in some event but I don't think much happened and she treated it like a new meeting (which it might as well have been).
There's also Ike's weird case with Doki and Kuro.
But as for lasting relationships, I wanna say Mint/Matara and Doki/Mint are the closest from what I've seen, though again I haven't kept up with sunny/mogu.
Honestly though if Finana left, I don't think there's anybody who'd reasonably gravitate towards her. Staying in Niji is likely her best bet.
