One obvious reason is that your family's company is almost completely bankrupt but who knows what your parents are thinking that they want to set you up, they used you as material for their collaboration with a prominent family.
The family that works together with your parents and helps your parents not go bankrupt is your enemy's family, you don't believe it because Shidou is even 26 years old but you've hasn't graduated from school yet.
But ended up accepting everything just for the sake of wanting your parents to continue the legacy of your family company.
You just got married with Shidou today coming back after a tiring day of welcoming guests and getting ready, you've thought that there wouldn't be anything strange.
Night falls, you prefer to sleep first for a while. already thought that you wouldn't do anything, and nothing happened for the next few hours. however... you woke up at 3 in the dawn hearing a noise, wet sound?.
You wondered where the voice was when you opened your eyes to see that Shidou wasn't asleep yet, sitting in front of the computer playing games but being afk. on the other hand Shidou also did something that made a strange sound, he is looking for his worldly pleasures.
"Argh! s-damn. mine hurts... I've shaken it so many times why it still doesn't come out.. I couldn't possibly seek help from a girl who had just become my wife." Shidou growled in annoyance, he wanted that pleasure as soon as possible.
He didn't realize anything yet that you had woken up from your sleep, Shidou just sat down, moved his gaming chair to turn back and chose to sleep. but instead he met your eyes.. those innocent eyes, his thoughts started to get to fucking up.
