A plot:
Lord Sullivan is learning that sometimes family can be an angel that you swore was your arch-nemesis but you may or may not already be in love with as your wife, a naive but well-meaning younger angel as your daughter, and an incredibly kind but traumatized human (?) as a grandson.
And of course, your security devil Opera.

Summary
Many said that all of hell was a blazing inferno.
But what if that were true?
In truth, demons are not fireproof.
So the netherworld lay blazing and dead, purely silent, while all who lived in it, good or evil, young or old, burned along with it.
And briefly, only a small number of demons remained.
Until sacred gold melted under the heat, and made way for another.

Summary
Kalego should’ve recognized the signs. Shichiro was only away these past six months and yet he somehow missed all the signs.
The nausea and the vomitting.
The odd cravings.
The weight gain.
His irrational mood swings.He was…sweet Devi he can’t believe he put himself in this situation. He was, missing Shichiro so much he was growing sick over it. How pathetic of him.

Summary
"[...] Sexuality, as well as a steady sexual relationship, was a perfectly normal occurrence for demons. Demons were driven by ambition and desire, and the latter category included sexual desires too. Tastes and preferences were not discussed, except in the form of friendly teasing. Who slept with whom, their gender, their roles, their habits between the sheets… all of this was considered a form of freedom that demons prided themselves on. Anxiety, nagging worry, guilt, stress, all aspects of sexuality seemed impossible to the demons. What was so difficult about pursuing pleasure together? Yet, this was by no means something to be taken for granted for the unfortunate pair of teachers at Babyls. Kalego sighed again, lost in his own version of despair. The problems in bed between him and Balam hadn't appeared overnight; rather, they had been progressive and worsening. Kalego had gotten a taste of the first signs when he noticed a certain delay in reaching orgasm during sex with his husband"
Basically Kalego begins to exhibit sexual dysfunction issues which affect his intimate life with Balam.

To try and explain, this is a fanfic based on both Mairimashita! Iruma-Kun (Osamu Nishi) and Genshin Impact (Hoyoverse). I'll explain more in the first chapter, but maybe try it out and see if you like it?
You don't need to know how both worlds work as I'll try my best to explain it all in the fic!

Порядок клану Наберіус завжди тиснув на всіх. Це не обійшов Кальєго звинувачуючи у зв'язку з монстром, який живе у світі людей. Це звинувачення призвело до того, що була спроба вбити непотрібну сім'ю в клані та магічна зміна якої ніколи не була.
Ірумі знала, що вона скарб лише для батька. Але вона була надто юна, коли зрозуміла це. Тільки ось тепер їхній маленькій родині треба мати справу з раптовими змінами та новими демонами, які вилазять із минулого батька
