I don't know if I want to see Yuri progress as it is right now :/
For starters, the girl hasn't even finished school ,the writer at times feels like she takes advantage of her naivety (I know it is mostly humorous, but it shows how easy she is to fool),not to mention the differences in maturity are too damn high. It also feels like Ayu is becoming too dependent on Hikari . I want to wait for a development in the MC so it doesn't feel as predatory, yet something tells me that won't end up happening.
