That second to last page gets me choked up every time. Easy to miss, but Mari keeps the print-club photo of her and Akko kissing hidden inside the battery compartment of her phone. I get it, but it still breaks my heart that their relationship is so secret.
I know right. Not to mention Sugi totally knows what's up!!!
When Mari is talking to her teacher (Naru-chan) about her future plans (after trying to switch to going after beauty school like Akko), Naru asks if she has a boyfriend. Mari replies that she doesn't, but that she's going out with someone, and then goes on to say she doesn't know what will happen with them. When you add in the current situation, which Naru already suspects is about Akko, I always thought that, without realizing it, Mari just basically told Naru that she's dating Akko.
Also, after graduation, Sugi is surprised to realize that Tamamin doesn't know what's up, so it seems at that point she's been assuming that their friends have figured it out.
But you're right. They are trying hard to keep their relationship secret, though they suspect that Sugi might know and that the others might figure it out eventually.
