Actually, 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 looks and deep voice, but despite hanging out with everyone, he wasn't interested in them. The only thing he was interested in was Guest.

7 Years Ago { Guest had been bullied for a long time } While Guest was crying, Vau asked: "Hey, what are you crying for? Are you being bullied?"

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

...Then, I'll be your Knight.

Guest: "Huh?"

Vau: "I'm saying that I'm going to protect you."

Since then, he had always protected Guest... Until middle school.

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

Vau: "Contact me if anything happens."

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

I didn't want to reach out... I didn't want to make him worry for no reason.

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