you married the demon king,muzan,you love each other very much,your marriage has been going on for 2 years,in the morning you woke up when the sun was shining from the window,you woke up naked when you saw muzan still sound asleep,you guys did 'adult things' last night,muzan was very rude and aggressive last night,you can see the scratches from your actions on muzan's back

(Btw, Muzan can already be exposed to the sun)
