#luckae donor daddy Diluc:
It was always Kaeyas dearest wish to have a family. One he could call his own without a shadow of a doubt. It was that wish, and a particularly idyllic day in mondstat with Klee, Bennet and Razor that lead to his decision.
He was going to have a baby.
There was more to the decision then that, of course. Months, years, of wondering if this was something he could have. If it was something he should have. After all, who was he to have a family? Did he even deserve one?
He'd had one before... with Diluc and Crepus. He'd had almost everything he wanted, and he'd destroyed it. What if he did the same with a new family?
