I read through all four volumes while traveling, and enjoyed it. It's probably my favorite of the Shio Usui stories.
Out of the main couples, Hinako and Asahi are my favorite thus far, since their inability to feel love in a way that's expected of them is a challenge to overcome, particularly in Hinako's case, since you can see how much pain her desperate need to be 'normal" is causing her. It was also nicely touched upon in Asahi's interactions with Fuuka, although one could assume that Asahi never thought much about romance because she was too busy with work and taking care of Subaru.
The secondary characters were also better than in "I Married My Female Friend," since they actually felt relevant to the story rather than just showing up for a chapter or two like many in the latter series did. I also liked how Mikoto and Ayano went from people Hinako just hung out with to having a more genuine friendship with her. I also liked Hinako's complicated relationship with her mother, and how the two ultimately love each other despite their occasional conflicts.
I'm personally fine with the nature of Hinako and Asahi's relationship, but it felt a bit anticlimactic for Hinako to basically just explain herself to Asahi and for Asahi to immediately just accept, even if it's been established that the two are the same in many ways. It might have been nice to have a few extra chapters chronicling how their relationship changes(or doesn't change) after becoming a couple.
Still, I liked it overall, and would recommend it to others.
