Looking for a novel I read before. The female lead went undercover near the male lead to obtain classified information. She was something like an assassin or secret agent, and approached him to complete a mission. She even blew up his base. She pretended to be sweet and weak to put his suspicions to rest about her...
It's very exciting, if you like suspense and the supernatural, you're in luck! There is an immersive feeling, and it is even more exciting to watch it in the middle of the night, hahahaha!
