Ajiichi has a thing for having a short haired hot girl in love with one of the MCs of their stories. Also, i don't get the Izumi hate, like yeah, she's just your average run of the mill closeted lesbian who is in love with her friend but its too afraid to act upon those feelings. Nothing out of the ordinary for this author. I actually like how she seems to be the gyaru version of Kurokawa, both of them seem to like Fujishiro a lot, but still feel unworthy of her love.
There's just one thing that this story is missing: Kurokawa, at this point of things, should find herself falling hard for Fujishiro, and struggling in confusion with feelings of love and passion that she doesn't understand. You know, just like Fujishiro has been feeling and acting towards Kurokawa? That. Afaict, Kurokawa is still stuck in "I admire Fujishiro, she's the perfect princess!" and hasn't shown any romantic feelings (or feeling of jealousy) towards the other girl. This cluelessness is blocking any progress in their relationship....
I thought this trip would help Kurokawa step away from her "admiration" phase of Fujishiro and maybe even a "Shit, i'm in love with her" moment, but we didn't get any of that. We actually didn't get anything. These last 3 or 4 chapters feel like unnecesary filler since we learned nothing new besides confirming Izumi is actually in love with Fujishiro which anyone who's reading this story already knew when they hugged in that cafe. I really hope the story develops more in the next few chapters cuz it feels like Ajiichi is following Citrus formula of just running around circles until a sudden dramatic development occurs.
