But honestly, it's probably going to continue to be a very slow burn between those two because even if they both decide to stop being useless lesbians, there's still the issue of their friendship. When you've been so close for that long, it can be a hard and scary transition to become lovers. As you can tell, I am clearly a yuri fan-girl and far too invested in this storyline as well, lol.
I agree, it is hard and sometimes the stuff keeps going and going a micro increments until it has turned into a relationship without the two friends knowing that they are in a relationship especially one with Ayano being a more reserved person who it is harder to tell people deepest secrets and a thick head like Miyoshi who might miss the fact they are basically in a relationship.
It's so funny that this point was brought up because, funny story, I actually know someone this happened to in real life. She was talking to a woman for a long time, they clearly had feelings for each-other, and eventually they just sort of lapsed into a relationship without my friend realizing it. The only reason she noticed was because the other woman made a comment to her at one point about their "relationship" and she was like "Wait, our what?", lol. Oh...we can all be useless lesbians sometimes.
However, back to this chapter. I rather enjoy Mari and Yuu. Mari's devotion to Yuu is just adorable, and Yuu is such a classic tsundere that I cannot help but find them endearing. Also, on a less wholesome note, did anyone else think "Wow, this is about as close to full-blown sex (foreplay not included) that anyone has come in this series thus far"? I'm all about it, lol.
