When Mike travels to Japan he does so to meet his deceased husband's family. We see his brother-in-law and niece reac to his presece and learn and grow from it. Mostly we see Yaichi go from being your typical homophobe to someone who is as a new person by the end of the 4th volume.
In My Brother's Husband we meet a special little family of 4. We have Yaichi, single stay-at-home-dad, landlord. Kana, Yaichi's daughter. Natsuki, Kana's mother. And Mike, Yaichi's brother-in-law.
We see each character (maybe with the exception of Natsuki) grow and learn about themselves and each other, in particular we see
Yaichi learn to accept Mike as his family and learn to see the wrongs done to LGB+ people in Japan.
While reading this you can easily understand that this was written by a gay man who as experienced a lot of difficult things in his home country. We meet different characters with different understandings of their own sexuality and who are at diffeent points in their acceptance of it.
My personal experinece of this was very nice. I found the characters very relatable, particularly Mike, although more related to his experiences of Japan than him being gay. As to his approach to life I wish I could be more like him.
Yaichi makes me want to believe there are good people out there who want to understand and support people like me and Mike.
