   Summary

   Tomioka Giyuu is ready to settle down.
   After a long string of awful relationships and watching his little nephew grow from a baby to a six-year-old child, he is done with waiting. At twenty-seven, with a stable job and a comfortable life, Giyuu wants to be a father. He doesn't need a partner to start a family. Hell, he's certain he can do it on his own. He just wishes he knew where to start.

   When his little brother proposes to his boyfriend, Shinazugawa Sanemi has only one thought on his head: well, fuck.
   It’s ridiculous, really. He had never been a man who cared about social expectations and perfect timing. But as he watches his brother getting engaged and the rest of his siblings growing into adults, maybe he panics a little bit.

   Then Kanroji Mitsuri insists on a reunion of their entire university friend group. After all, it's been half a decade since the seven of them were in the same place together.

   Or: Shinazugawa Sanemi and Tomioka Giyuu decide to have a baby together after years of not seeing each other.

   (This story might feel a bit ooc regarding canon because they are older and in a modern setting, but it makes sense in context)
