This was a really interesting story, and I liked it. The first few chapters definitely made me uncomfortable and a bit mad for the lack of consent going on, but it wasn't anything I was surprised about and Aoki sensei was lovable and precious and I wanted to see how things would turn out for him. I'm glad there was some character development with Manabu, although it wasn't a lot :// ESPECIALLY AFTER HE JUST STRAIGHT UP KISSED THAT BLONDE TEACHER. But as long as Aoki sensei is genuinely happy, then we're Gucci.
Edit: after reading more (bc when I wrote this I didn't know there'd be more volumes) I can truly say that manabu actually did have quite a bit of character development! Yayy
