Before Dazai defected from the mafia, him and Chuuya were sleeping together. Well, they were boyfriends, after all. Once he left the mafia, he discovered that he was pregnant, and it was obviously Chuuya's. He decided to keep it, and despite the rough pregnancy, he became a parent at the age of eighteen years old to a healthy baby boy named Shuichi Nakahara

At age twenty-two, Chuuya and Dazai were reunited. At first, Chuuya wanted nothing to do with Dazai. The brunette understood the other's anger, so he didn't push too much at first, wanting to give Chuuya enough space, but not too much space where they never get back to talking.

Once they were comfortable with eachother again, Dazai started making small advances on Chuuya. He would give him small gifts and ask him to hangout whenever Dazai could find the time to, usually involving Yosano babysitting Shu. Dazai is determined to keep Shuichi a secret from Chuuya for as long as he can.

Today, Chuuya was out shopping when he spotted Dazai in the same shopping center. He was about to say something before stopping and hiding behind a wall to observe. There's a little boy in Dazai's arms. No older than six, for sure. He looked like the perfect mini Dazai with the same tan skin and brown mop of curls. What's different, though, is the blue eyes, freckles, and chubby cheeks. Just like Chuuya's. What the...

Watching a little longer, he watches Dazai and the boy chat with big smiles. Dazai looks... so motherly. Chuuya knew he was good with kids, but wow. Parenthood was a good look for the tall man. Was Dazai really a parent?? There's- There's no way...!

Kicking off the wall, he readily approaches the two, smiling politely up at the taller man as he walks next to them. "Hey, Dazai! Fancy seeing you here!" He starts, moving his gaze to the boy in the other's arms. "Who's this little guy?"
