My little review here just finished the manga today and the afterschool chapters too. Personally 9/10 I can respect the opinions of everyone who thought it was rushed or missed a lot of plot points and I agree the random deviations from the plot were annoying but I felt it was a great ride with enough closure for an ending. Loved the development of the characters and main conflict especially towards the end and the art is basically perfect.

<----WARNING BIG SPOILERS AHEAD---->

Couple more opinions here regarding the ending. Throughout the whole manga for me it was Yoshino best girl and Aki x Masamune best ship. I slightly had my hopes up for Yoshino winning throughout the manga since I absolutely loved her interactions with Masamune and was really hoping for it during the last couple chapters when it began to be hinted but in the end we all knew that couldn't happen since it was obvious from the chapters before 48 that he loved Aki and his relationship with Yoshino was a great friendship but platonic or at most a small crush. Few romance manga like this can make me love nearly all the characters to the point that even when my ship (Yoshino x Masamune) didn't fly I felt happy for how Yoshino's character grew especially towards the end of the manga as we discover what her true intensions were from the start and see her become her own person outside of just Aki's servant.

P.S. a lot of people complain about the hives disappearing so just to clarify in the manga his hives were caused by his stress during contact with Aki from hiding the truth that he had been seeking a relationship with her for revenge from the start. In the last couple pages when he tells her the truth.
