The female lead is very powerful but keeps a low profile. Then she returns to her hometown or somewhere she used to live. Ideally, she's an assassin or a hacker.
Who knows, if we join forces, we have the world. The heroine is really domineering, she keeps abusing the scum, it feels really good, her breasts are all clear, she has a cold personality, but she is really handsome, and the hero is also super doting, and the two of them feel a bit like Mr. And Mrs. Smith~
