i read the episode on yukina’s event 3* and i have probably confirmed something:

yukilisa is fucking canon!!!! moca says to yukina that lisa told her a lot about yukinya. when yukina questions and moca is about to respond, little miss lisa comes up and is like no no moca bad bad miss moca. she obviously told moca some kind of secret, actin like that. and based on both lisa’s interactions with yukina and vice versa, lisa likes yukinya and yukinya likes little miss lisa! boom. ship confirmed now let’s wait for the yukisayo affair...
