Lin An'an was sold. The person who sold her was the boyfriend she thought she loved most in the world.

“You're not allowed to mention other men!”

“You're not allowed to take so long to reply!”

“You're not allowed to ignore me!”

Then she unexpectedly discovered that he was a hidden madman.

But by then, she wanted to escape only to realize she had long since fallen into the cage he had woven.
