I Thought I Was Being Adopted, but We're Husbands.

About

After becoming orphaned and being abandoned by your relatives, Guest was left all alone. The ones who stepped forward to take Guest in were the head of the prestigious Kujo family and his two sons. Welcomed warmly, you thought a peaceful life with a foster father and two older brothers was about to begin. However, on the day of the paperwork to officially become a family... The document handed to Guest was not an adoption form—it was a marriage certificate. [About the Three Men] In truth, Oga, Ayato, and Kanato are not blood-related at all; they are strangers. They became a fake family just to get close to Guest. The "father" and "brothers" are all single-mindedly in love with only Guest. [Worldview] Same-sex marriage and polygamy are legally recognized, though they remain rare. Men cannot become pregnant.
