I don't think she'd care, especially now that Akira has the blackout card. I do wonder if Maki knows. Actually, that's a good question, I don't remember how they are in knowing about eachother at the moment.
Cause Haruka and Maki have sex with Akira (during the fix Maki trip), but I don't remember if Maki knows that Haruka and Akira are a thing. Same goes for Haruka and Sara (that have sex with him two different times). Then we have Maki and Sara knowing about eachother, one would guess that at least Maki knows about Sara since she keeps calling Akira her boyfriend so much that Yuki feels the need to hold back. And since we mentioned everyone else, I don't know if Yuki knows about Haruka and Maki either.
Do you know what I'm also curious about? If and who's going to find out about Kaori's kiss. It's clearly a thing since it was revealed to everyone at the church last update, and it would have been revealed to Niki if Nao-chan hadn't interfered.
