Summary
Perhaps to be saved is not to have someone forcefully drag you from the depth of your mind that you’re drowning in, but to have someone convince you to open your eyes beneath the water—no matter how terrifying it is—and allow you to realize that you can only breathe on your own.
Or: A love story between a drowning author and the one person who forced him to breathe.

Summary
Chuuya is on the crux of a realization. A disturbing, vindicating realization. He almost doesn’t want to believe it. Scratch that, he doesn’t want to believe it. But at the same time… he kind of really does. And the evidence is… kind of hard to ignore.
-
Or, Chuuya comes to some... interesting conclusions about his partner.

Summary
He reaches the master bedroom, but instead of turning the doorknob and heading inside, he stares at the door, waiting patiently. Even though he hasn’t notified the owner of his visit, the room door bursts open, revealing a redhead with very few layers. He must have come home early from work. The smell of alcohol lingers on him. His cheeks are tainted pink. He's always been a lightweight after all.
Chuuya Nakahara. A mafia executive.
“Dazai you bastard! Didn’t I tell you not to break into my apartment.” he says with a deathly glare— a predictable threat.
OR
Dazai once again breaks into Chuuya's apartment, however this time it ends slightly differently.

Summary
Dazai has never believed he has a soulmate, most people ‘swapped’ with their soulmate multiple times a month since about five. Kids would wake up in another person's body and live that person's life until they swapped back, typically meeting their soulmate’s friends and parents. It was always a happy occasion. Some rumors even say if you perfectly connect with your soulmate, you can control the swaps. Yet Dazai never had this core experience, not until he was seven.
Or
Dazai and Chuuya are young children who never thought they would have soulmates. They are soulmates, cue fluff, angst, and plot.

Summary
Chuuya smiles at the memory, reliving the night in his head. “He’s a second year university student. He’s only two years older than us and in his second year. He told me it's because he skipped a year in high school. Now that I think about it he must be very smart.”
“Big deal, I could have graduated university by the time I was fifteen.”
The five times Chuuya was courted by people and the one time it was Dazai’s turn.
Or: Throughout the years Chuuya is approached by different people interested in him, Dazai loses his mind while being completely oblivious as to why it bothers him so much.
Or-Or: Chuuya’s long journey of finding his Type™.

Summary
Request for : guest (Sofia)
He opened his eyes, barely. Just enough to glance at the tabs still open on his browser from the last time he’d spiraled.
Looking for a Sugar Mommy or Sugar Daddy?
The tab blinked pink at him.
What wouldn’t he do for rent and a warm meal?
Would he cook? No, that’s too far.
But like—kiss someone? Sure.
Dress up a little? Whatever.
Pretend to be dumber than he is? God, that’s just normal.
If they wanted him to cross-dress and coo at them like some airheaded girl? Fine. Done. He could wear a skirt. He has nice legs. He’s worn worse in worse places for worse reasons. If they wanted him to play arm candy and simper and bat his lashes in public?
Whatever. Pay my rent and call me sweetheart, daddy.
OR
Dazai is broke. BROKE. So what could someone do other than get a sugar daddy?
Lucky for him, through all the creeps he finds a hot man with head hair, heterochromia, rich.
Very rich.
Unlucky for him—little does he know that this man may or may not be the port mafia boss—and let’s just say, the truce may not be very stable.
FINISHED (Prequels etc (like in the same AU may come out per request!!)

Summary
After transferring to a new school from an all omega-beta school, Chuuya struggles to learn things about himself dealing with trauma from his past while simultaneously adjusting to his new life and an irritating new classmate.
Dazai is learning to deal with the weird urges he finds himself having after accidentally bumping into a rather annoyed omega while struggling with the idea that maybe, just maybe, there's something for him to live for after all.
What is there to do when two souls that have been intertwined upon their first meeting begin to understand that there is a such thing as soulmates, all it takes is fate and maybe a few accidents to guide you to the right place? What do they do when they learn not only more about themselves, but heal each other in the process?
In other words, Dazai and Chuuya bicker and fight but discover that they are fated, both deny it but cant deny how much better they feel with the other.
