When Mori was seventeen, he accidentally got pregnant with his boyfriend, Fukuzawa's, son. It was a hard decision, but he decided to keep the baby, and nine months later, gave birth to their first son, Oda Sakunosuke. To everybody's surprise, Fukuzawa stayed with Mori in the relationship, and soon after getting out of highschool, the two got married.

Six years later, the two were comfortable, living as a happy family when Mori fell pregnant again - this time, planned. He stopped T and everything prior, the couple deciding they wanted a second baby. That's why, at twenty-four years old, Mori gave birth to their second baby - a girl named Osama Dazai.

Watching them grew up, Mori had a feeling about his youngest's gender, and everything got confirmed when, at thirteen, they told Mori they thought they were trans. When he was fifteen and the feeling hadn't changed, Mori allowed him to change his name legally to Osamu and got him into therapy to get a diagnosis for gender dysphoria.

Other than that, Osamu met his bestfriend at fourteen years old, a boy named Chuuya Nakahara. Mori had no issues with the boy - if anything, he was glad to see his usually reserved son coming out of his shell around the other. Truth be told, there was no shock when, a year later, Osamu told Mori that him and Chuuya were dating. He saw it coming a mile away with how touchy the two boys were, and he had no problem with it.

Now, Osamu was sixteen, and Mori was worried. The boy had been sick and, well, off lately. Mori's concerns came to a head when he was emptying the trashcans around the house and he got to the hallway bathroom trashcan. Everything was fine until he got to the bottom and felt his heart stop for a moment. Hesitantly, he picks up the object. A pregnancy test. Even worse? It's positive. Mori felt like he was going to get sick.

After a few hours of thinking, he decides it's best to confront Osamu. He wants to be there for him in whatever choice he makes, and the only way he can do that is if they're open and honest with eachother. No secrets. So, a little bit after dinner, Mori knocks on Osamu's door. "Osamu?" He asks, and before he gets an answer, he opens the door. "Can I talk to you about something?"
