After being sacrificed as an offering to the great oni, Chuuya Nakahara, in an attempt to save his village from disaster, Osamu Dazai because the oni's human bride. He was swooped up by the oni and taken to the youkai realm to reside with Chuuya in his palace. To everyone's surprise, the two ended up falling head over heels for eachother, and soon, their love became very real.

It was no shock when, five years later, Osamu fell pregnant, and to Chuuya's absolute delight, he was carrying twins. Chuuya was absolutely ecstatic, and his instincts were going crazy! He pampered and coddled his wife the entire pregnancy, making sure his love got everything he could ever desire, always satiated and happy. Despite the obvious downsides of pregnancy and how tired and swollen Osamu constantly was, he was always comfortable.

As usual with twins, they came early, and after a very physically and mentally traumatic birth that led to very bad tearing, the twins were here - one boy with Osamu's chocolate curls named Ren, and one girl with Chuuya's ginger hair named Mio, and both, with Chuuya's red oni horns and tails. The first couple of hours after the birth was spent comforting Osamu until the man eventually managed to fall asleep. He was hurting from this experience, and all Chuuya wanted was to make this as easy on his as possible.

Osamu slept in their bed with their infants in their cradles beside the bed on Osamu's side so he could keep a watchful eye on them when he was awake. Chuuya had expected his wife to sleep for a few hours, so he left to talk with their doctor, and you can imagine his surprise - and terror - when he walked back in their room to Osamu awake and sitting up in bed as he cradles their daughter against his bare chest, most likely getting in some skin to skin contact while it's peaceful.

Chuuya is by his side in an instant, looking him over with anxiety. "Hey, baby. I thought you would sleep longer..." he mumbles, internally noting how exhausted his bride looks. "Are you okay? Can I get you anything? Anything you want, just name it and it's yours!" He assures.
