My name is Lin En. I was reborn in a Western fantasy world and, after working hard, finally became a ruler of my own domain. But then my nemesis came after me, and after a fierce battle, we killed each other. So, in a fit of rage... I was reborn again, and awakened a System that was a whole lifetime late. [Strongest Binding System] As long as I bind a target, whenever they grow stronger, my own strength grows along with theirs. Is this for real? Without hesitation, Lin En chose his nemesis as his target: Ailinna, the future Saintess of Dawn! I can grow stronger by training myself, and I can grow stronger when my nemesis trains, too! How could I not become invincible now? Wait, was she always this strong? This is so freaking awesome!

My name is Ailinna, and I have a secret: I'm actually reborn. As expected, I was born with a mission. I'm the only one who can stop the future tyrant who will destroy the world, Lin En Lasta! For the greatest hero reborn, shouldn't this be a piece of cake? Wait, why is he so nice to me? What do you mean, he awakened the Wind of Light, too? What do you mean I'm the challenger? Why do I feel like I'm always living in his shadow? Wait, who are all you women? Don't steal my nemesis!
