I'm Really Not Green Tea

The subject matter is very novel, it is the awakening of the consciousness of the two men in the novel, but the name is very confusing. The female protagonist, also known as the "second female lead," repeatedly goes in despite knowing that there is danger. If the male protagonist, the "second male lead," hadn't saved her in time every time, she would have been killed by the bad guys. Moreover, the female protagonist feels that she has no brains many times, and suddenly becomes like a holy mother, making random guesses and making decisions, and she becomes very upset when she sees the heroine.
