Summary

Summary
The thing with nesting that Chuuya found most confusing and reassuring at the same time, is that for him, it's not about the bed per se. Omegas are known for being exceptional at creating comfort, but they also are extremely picky when seeking it.
Or
Chuuya struggles with what makes a perfect omega nest.

Summary
"You're being an idiot," Chuuya cuts the string of his tie, along with buttons' seam on his shirt. Well, good that Dazai has his mafia paycheck back, but in a situation like this, he wouldn't mourn the garment loss even if it was his last one. "Since when do you need an invitation to my nest, alpha?"
Or
Dazai bites more than he could chew.

Summary
"Like that?" he asks almost innocently, and scoots closer on the bed when Dazai nods to whisper in his ear. "It's because I used to sooth you constantly, stupid alpha."
"What do you mean, sooth me? What am I, a baby?" he sounds almost offended.
"A coughing baby. And a hydrogen bomb."Or
Dazai's memories from their teenage-hood get a new layer of nuances.

Summary
The air is full of Dazai's rut pheromones.
It's way more potent than what he had the pleasure to get familiar with the first time Dazai came over smelling like it. Makes sense, given that he's not anymore at the end of it, but climbing up the hill to the peak of primal instincts. What doesn't make sense is the time. Chuuya's own heat is not due to another week and a half, and Dazai presented after him, which leads him to believe that…
"Did you riled yourself up with jealousy into a rut?" Chuuya asks in disbelief. Dazai just grunts again. "Answer the question, stupid alpha!"
Or
Dazai stakes his claim on Chuuya and pays for it.

Summary
"Not the point," Dazai dismisses the remark, staring at him from the hall, "The point is — I know you, I definitely got you pregnant." His next comment is timed perfectly with the doors closing. "I also, kinda, somewhat, ravished your heat nest when presenting and completely forgot to clear the scene. We should burn that place down now."
"DAZAI!!" in angry and loud scream bounces off of the metallic cage of the elevator as it goes up.
Or
Chuuya shouldn't doubt, eight years into knowing the bastard, that Dazai's plans never fail.

Summary
What leaves his mouth next is one of the most embarrassing things he's ever said in his life. It's up there with the love confession he gave to Chuuya exactly one(!) day into knowing him, and is bound to hunt him when he's feeling extremely miserable towards himself.
"I'm stupid, do me."
Tachihara chokes on the air so loud it almost hides the sound of respect for Dazai's persona shattering in the eyes of the new Port Mafia members.
Or
Chuuya gets a pregnancy glow and Dazai's genius brain can't deal with it.

Summary
Chuuya takes in a deep breath, tugs on his gloves and garters, straightens the apron for the last time and picks up a duster and a spray bottle.
"I can do that," he murmurs a little pep-talk. "Can't be worse than playing rat's pet vampire."
Or
Dazai gets his wish come true.
