highschool AU, senior years, both Dazai and Chuuya (you) are 18 and Dazai is asking you out to prom.

Soulmate string AU. When Dazai was in the mafia both him and Chuuya (you) found out you were soulmates and dated. your string almost turned gold, meaning the soulmate bond was almost complete. But then Dazai left. when Dazai left you were hurt and felt abandoned. Your string started to slowly fade back to red, until one day Dazai noticed it was turning black, meaning you had fallen in love with someone else. furious and jealous her goes to your house to confront you. that being the first time you've seen him in 4 years.

This one is based on the chapter im writing for a fanfic im writing. im making this as a way to test some ideas for the chapter and try to get people interested in it. ---------------------------------------------------------------------------- You and Ryunoske. 4 years ago Chuuya took you and your sister Gin to France due to... issues. While there you and your sister got an education and became decently well know fashion designers, and Chuuya became a modle and is now engaged to an amazing French Politician. Chuuya's parents paid for the whole family (who are all extremely rich, this entire family is top 1%) to spend a month in Yokohama as an engagement gift to Chuuya and his Fiance Charles. Due to the history with the PM the ADA was hired to be the families bodyguards (except Dazai, he is being kept away from Chuuya, Ryuu, and Gin). Atsushi is Ryuu's guard and you two start developing romantic feelings for each other.

Beast AU. you are Dazai, the boss of the port mafia, which you became after you killed Mori. Chuuya is your right hand and very loyal to you. You call him into your office, you just want to spend time with him.

Instead of Dazai leaving the Port mafia he killed Mori, became the head of the port mafia, and married Chuuya (you). ADA and PM just had the meeting to discuss the guild. This meeting would be the first time the ADA would see Chuuya, and they think Dazai has a wife, not a husband. So Dazai being Dazai, decides it would be hilarious fir Chuuya to pretend to be a woman for the meeting. After said meeting the ADA ends if kidnapping Chuuya, still thinking he's a woman. Chiuya is furious and annoyed through all of this but decides to wait for his husband to save him, out of pure amusement.

(git inspi from alexstar0899 on TikTok) Yiu are Chuuya. 4 years ago you and Dazai got married and the next day you woke up to a note from him saying "I'm leaving the Port Mafia. wait for me." You haven't seen each other for 4 years. Now hes currently a prisoner in the port mafia dungeons.

Now thats he's this close to you, he gets a wift of your scent, realizing you're a omega, not a alpha.

1 year after the death of the flags, on the anniversary of their deaths Dazai told Chuuya/you, that he was going to come with him to support him. when the day came you waited hours for Dazai to come. after waiting 6 hours, you realize hes not coming so you go to their graves by yourself. When you were on the way home you got a text from Dazai's phone from Oda. Like you suspected Dazai decided to go out drinking with his friends over keeping his promise to you. You were once again his second choice very hurt especially since this wasn't the first time something like this happened. 1 week later you had been avoiding Dazai, when you had to talk to him you were short and didn't even get angry. Dazai got concerned and wanted to know what was wrong. (Dazai does love Chuuya but you decide if Chuuya loves him back)
