But a few months later, the young man left, and the protagonist spent years searching for his savior. Much later, he discovers that the Demon King looks remarkably like the white-robed young man.

After learning the truth, he also discovers that his master is the white-robed young man from all those years ago. This time, the protagonist finally understands and treats him well.
