So you know how after the final arc, Tengen and his wives have a baby and Giyuu was the first to hold the baby?? Yeah, I think about that often.
How you are visiting the Tengen’s and when Giyuu holds their baby, he just has this look of amazement and wonder. There’s a sparkle in his eyes bc holding this tiny little human is causing much more emotions than he thought it would. Holding out his finger and the baby wrapping their little fist around it. Giyuu turns to you and just has this look of “please we need to have one of our own. I need this in my life with you” and it’s just the sweetest thing.
Later when you’re both home, Giyuu immediately brings it up. Saying he never knew a child could bring so much joy. Didn’t realize he had these kinds of feelings until he actually held one. Sincerely asks you if this is something you’d like to do with him, to start a family together.
