In the palace, Su Jin was a little eunuch who could be bullied by everyone. Even the maids dared to insult him, but only the seventh prince always secretly stuffed him with snacks. But no one knows that Su Jin's "eunuch status" is fake - he is the son of a former general. When his family was framed, he faked his body and entered the palace to avoid trouble.
On the surface, he is cowardly, but in fact, he secretly sets up a network to collect evidence of the current prime minister's rebellion. Just when he was about to hand over the evidence to the Seventh Prince, he discovered that the Seventh Prince had already known his identity, and even the Seventh Prince's mother and concubine, the "victim" of the family's injustice case back then, was the mastermind behind the Su family's murder!
What's even more subversive is that every piece of snack the seventh prince stuffed him had a secret message hidden in it. It looked like he was trying to win over him, but in fact he was using him to lure the snake out of the hole, using his hand to get rid of the prime minister, and then put the blame on the remaining members of the Su family. Su Jin had a backup plan early on. He deliberately leaked false evidence and made the seventh prince and the prime minister kill each other. In the end, he took advantage of the situation and forced the palace to use the evidence of both parties' crimes. He put the young prince in power and became the "real boss" behind the scenes.
