Ryuu-jin Aoki, one of the top 10 powerful people in the world, found that his favorite character in the novel named Yume suddenly became a villainess. For this reason, he used his wealth to find the whereabouts of the author. But to no avail, he failed. One day, the newest chapter of the novel, condemned Yume, who was punished into slavery. This is where Ryuu-jin's patience got broken. Luckily, a miracle happened where he was given a choice to live in her world and save her. So he became Ryu Xanastre, a self-made male lead who will save the damsel in distress. "Wait for me my princess," he said, "if the male lead abandons you, then I'll be the second male lead and protect you."
