I think my main issue was how awful Watanabe has treated Yoshioka. Be it in her thoughts or not. Meanwhile, Yoshioka turned out to be this nice girl, a great sister, and overall a good person. All because she didn't fit with the narrative inside Watanabe's head. Now doesn't that sound familiar huh? Now I'm not sure if it's a clever setup or not, but if it was, bravo.
Regardless, this chapter was a nice step in the right direction. I just want to like Watanabe. I already like Yoshioka. Let me like the other protag.
I think that's what the artist is aiming for here- note we've seen no actual yuri so far in any of the souer relationships. I'm pretty sure this manga is explicitly intended to make Watanabe grow as a person neon just seeing things through yuri goggles. This last chapter pretty much proves it, imo, with the president actually telling Watanabe that she's essentially a character too. And I think Yoshioka is the perfect person to pull her out of this shell she's made for herself and show her exactly that.
I don't know, that's just me. I don't love Watanabe, but I don't hate her the same way most people here seem to. Maybe because that's how I've seen the manga from the beginning...I've never thought it was just going to be about her staying some crazy yuri fangirl. She's a flawed character, sure, but the fun is in watching her grow, and I honestly can't wait to see how that pans out. She's clearly already starting to see Yoshioka a little differently just based on her reactions- I think it's more that she's kind of given herself a mental block (hence the title), but her body and heart are clearly on a different page. I think the main part of this manga will deal with Watanabe learning to get past that and really see herself and others as more than characters in a manga.
