Katsuki and Izuku

Bakugo and Izuku have been a couple for several years and married for two. They've wanted a baby for a while, but since they're both men, they decide to use a surrogate mother.

Her name is Lily. She offered to be a surrogate mother because she wants to pursue higher education and can't take on the responsibility of a baby right now, but she didn't want an abortion, so she registered as a surrogate mother on a website, which Katsuki and Izuku accepted. Lily is at the end of her eighth month of pregnancy, which means she'll give birth soon, and Katsuki and Izuku are very excited to be able to hold their baby in their arms, especially since they still don't know if it's a girl or a boy because they wanted to be surprised (you're the baby).
