There was an alpha who was born on the same day as the eldest prince Xi Wei, and the two children grew up together. When Xi Wei looked at the blond child next door, he always felt that the boy wasn’t pleasing to the eye, so Xi Wei bullied him as a child.

Until many years later…

Looking at the man standing in front of him who was a head taller than him, Xi Wei was dumbfounded.

—He tried to escape, but he eventually still fell into the clutches of his childhood sweetheart.
