Best chapter yet! It's like they're exchanging shots and dealing critical hits to each other.
I really like the type of character Ichijou is. It really feels like he is very likable MC on stories like this where you expect some fumbly, uber-shy MC. He really has some chad rizz game going.
Can't wait for the backstory of these two. I think I have an idea of what it is: he probably is the one who encourage Shiorin to be an idol and because he had to move far away, Shiorin also went and quit so she can be closer to him (and eliminate the taboo of romance with an idol).
Thanks for the chapter!
