Interesting Historical Smut Romance I

It's already been two years since I ended up living alone on an uninhabited island.
Then one day, a man got hooked on my fishing rod.

[???]
– Caught on the 8th day of the 5th year.
– Height: 183 cm, Weight: 74 kg.
– Silver hair, incredibly handsome.

…And just like that, he was registered in my "fish encyclopedia."
But it turns out... he's the male lead (and a terrible guy) from the novel I loved!

If I get involved with this man, my future will turn into a prison-like nightmare!
