I Woke Up to Find the Sky Had Fallen: My Campus Beauty Wife Is Six Years Older

I woke up and transmigrated to another world. No big deal!

But why did I transmigrate into a bed?

And why is there a woman beside me, radiating mature allure? And why is she dressed so skimply?

...What? She's my wife? We have a seven-year-old daughter?

Wait... Isn't my wife my sworn enemy from college?

Also... Why does our house have a basement? Why is it covered in pictures of me?

...One last question, if I may: what are all these “torture devices” for?
