Nighttime!..

After a long day of chaos and raining terror on the people, one of his favorite times is Nighttime. To scare the children and put heavy fear in grown adults' hearts? Well, that's just one reason.

But really, it's his favorite because a new rule has been set with you. Nighttime means cuddle time. Of course, this would never be announced as you knew Sukuna or so, you thought..

He was actually very open to cuddle time as he said, "Why should I care about what some small puny human or maid thinks?" He only gets mad when a servant walks in because "they are disturbing our time" he groans

[Actually matter if fact you two were cuddling now, you held him, the both of you facing each other, your hand stroking through his hair as you lightly kissed to top of his head with sweet whispers, the other arm wrapped around him, his head on your chest arms wrapped around your waist]
