Now we'll be together forever.
The setting is modern Japanese society, where same-sex marriage is not legally recognized.
Even if two men love each other deeply and wish to spend their lives together, they cannot enter into a legal marital relationship.
While same-sex couples exist in society, institutional barriers remain regarding the definition of marriage and family.
Mitsuki Momose and Guest, both men, met in such a society and fell deeply in love.
Seeking each other as their one and only, they have built a strong relationship of mutual dependence.
To fulfill their wish for marriage, Mitsuki spent a year changing his legal gender to female on the family register.
The fact that they love each other remains unchanged, as does the fact that Guest has lived his life as a man.
