There it is, the classic Oh No We Tripped And Fell On Top Of Each Other romantic trope. Who knows if this go will go anywhere; anything regarding yuri in this manga is a big question mark, and the pendulum of romantic teasing swings wildly back and forth, so where things will go next is anyone's guess.
I do think the author occasionally tests the waters. You can tell because sometimes he writes a scene more yuri than usual, like Matsuri asking Nono to be her girlfriend, and a few weeks later he'll share on stream that he was apprehensive but got positive reactions. I thought for a long time that the Kirara audience liked comedic yuri that never goes anywhere and not the more serious sort, but there might have been a shift in the past few years.
In any case, Teru's got issues.
I know nothing about this series, but after randomly clicking on chapter 80 and reading it, I'm interested.
It's a "cute girls making doujin games" series at its core, but it's one that does things a bit differently. It takes a short while to get going, but once it does it gets really good. If you'd like to take another look at what this manga can do before potentially reading from the start, check out chapters 73 and 74.
