Personally, I didn't get the sense that the protagonist has any feelings for anyone. If you'll notice, they carefully avoid ever actually using the word "love" between the two women.
You could probably infer that there's romance there, but at that point it starts feeling like subtext. Strong subtext, but just subtext nevertheless. Maybe it's just clumsy writing.
Trust me, I really wanna yuri-goggles it up here and get some good gay reads in, but I'm just not feeling it here. Clearly other people feel differently, but clearly I'm not the only one either.
