Spoiler
He does get pregnant in the side stories after it ends but he never has it. Its only revealed that hes pregnant and they have a gender reveal party. That's literally the last chapter of the side stories tho so we aren't getting anymore. I was a but disappointed too but the story is still excellent.

Just finished the novel, phew 10/10 amazing, biased though. Unbiased perhaps 9.5/10. No spoilers review: It really explores the complexities of love. Makes you feel all the emotions. I cried in heartbreak, smiled at heartwarming moments, and laughed joyfully all within the same chapter sometimes. Here's a really good translation link for yall who wanna read. I recommend starting from the beginning bc while the manhwa is good, the mc is a quiet person and a lot of the story is his internal thoughts and dialogue. The novel does a better job at communicating his true thoughts and feelings which with a relatively non speaking mc is essential. But for those who really want to know, season one of the manhwa ends with chapter 11 in the novel. https://sites.google.com/view/dd-dark-mode/dd-all-chapters?authuser=0
