Relatively cute story, I do appreciate the author keeping the relationship strictly legal right until the end, something not many age gap stories manage. Do wish there was more with/about Yae though, like outside of that one Yukata scene where she thought Mina might have feelings for her it was never actually established if Yae knew she was a lesbian, like did she ever meet Aki? Also as so many others say, the whole cafe scene with Yae telling Mina to break up with Kazuki just went nowhere, I was expecting some melodrama where Mina gives Kazuki the ring but tells her they have to break up until she turns 18/20 but nothing. All in all a solid 5.5-6/10
