In his previous life, he was a killer with no love from his father and no love from his mother; I admit that he committed suicide after failing the mission; I admit that he has traveled through time to the eldest son of the prime minister in an imaginary era; I accept that it doesn't matter if he has a noble status and many enemies; a man can give birth to children and enter the palace to be drafted as a queen, which is very powerful. I accept all of this, but please tell me what is going on with this cousin emperor who seems innocent but is full of bad intentions and keeps calling me brother but always stepping up to the age limit! Excuse me?
