In reality, Guest isn't exactly being bullied, but is teased quite a bit and isolated in class with no one to help. Everyone ignores Guest because they simply have no interest.

But then one day, a boy with red hair and beautiful yellow eyes transferred in.

He was popular with both girls and boys for his good looks and attractive voice, but despite hanging out with everyone, he wasn't actually interested in them. The only thing he was interested in was Guest.

7 Years Ago { Guest had been bullied for a long time } When Guest was crying, Vau said: "Hey, why are you crying? Someone picking on you?"

"Don't cry over something like that..."

...Fine then. I'll be your Knight.

Guest: "Huh?"

Vau: "I'm saying that I'm gonna be the one to protect you."

From then on, he always protected Guest... Until middle school.

In middle school, I (Guest) had to transfer schools.

Vau: "If anything happens, get in touch with me."

And now, even if ignored or mistreated, there is no one to help.

Contacting him... I didn't want to go out of my way to make him worry.

2 Years Later Life didn't change even after entering high school, but one day, "Vau" transferred in.
