Osamu Dazai was an orphan born in a poor village terrorized by an oni named Chuuya Nakahara, and in an attempt to appease the oni, he was offered up to the man as a bride shortly after turning eighteen. The oni, taking pity on him, took the offering and agreed to leave the village alone, taking his bride to his palace in the youkai realm where he got to know the human. It didn't take long for the two to get to know eachother, finding that their enjoy the other's company, and, eventually, the duo fell in love for real. Now, Chuuya is happy to call Osamu his wife - the love of his life.

Five years later, Osamu fell pregnant with Chuuya's babies, a set of twins - one boy named Ren with Osamu's chocolate curls, and one girl named Mio with Chuuya's ginger locks, and both with Chuuya's oni horns. Chuuya had always been possessive with his human - humans were fragile things, after all. But said possessiveness only increased after Osamu became pregnant - his instincts flaring up because of it. When their children were born, it eased up, but it never went away. Point is, he's always been possessive over his love.

Well, now, their babies are three years old, and for once, Osamu is getting a break from caring for them. See, he's always done everything he could to be the best mother for them, closely following every traditional rule his village had taught him to follow in order to be a good wife. He's gotten better at not listening to every rule, but he still follows most traditions. Well, today, Chuuya had to go meet with some higher ranking youkai. His older sister, Kouyou, decided she wanted to spoil the twins today, so she insisted she take them off the couple's hands, saying she'll return them in the afternoon the next day.

Because Osamu had nothing better to do, he decided to tag along with Chuuya today, something he's never really done but is allowed to do as Chuuya's wife. It was pretty boring - just a formal get together in order to keep up Chuuya's image and whatnot. Well, there was one youkai there - a woman who Osamu didn't care enough about to figure out what exact type of youkai she is - that just couldn't keep their hands off of Chuuya, and to say it was irking Osamu would be an understatement.

He could feel his blood boiling as the afternoon progressed and the woman was only getting more daring. Chuuya denied all of her advances, of course, but she couldn't seem to get the hint. Something must have clicked in the human, because the rest of the night was spent directly beside Chuuya, one part of him always touching his husband as if reminding everyone that he's taken. Chuuya, of course, noticed this shift, but didn't say anything, instead reciprocating the touches and always having an arm around his lover's waist.

As the get together comes to a close, Chuuya and Dazai get into their carriage, now alone as they're driven home. Alone in their little cart, Osamu full body clings to Chuuya, holding him tight as he peppers possessive kisses and nips all along the shorter's shoulders and neck. "Darling..." Chuuya finally speaks up, sighing. He's never seen Osamu get like this before. He brings a hand to the other's thigh, rubbing over the fabric of his wife's dress soothingly before pulling him into his lap entirely and wrapping his arms securely around him. "May I ask what's bothering you?" He asks, though, in all honesty, he's basking in the other's attention - his instincts going crazy at such displays of pure possessiveness over him.
