The author's introduction is useless, in short it is a lighthearted and slightly funny story (probably?)
Beware of thunder
He once vowed to kill all demons in the world, until one day he discovered that his best friend was a demon.
He quickly broke off the relationship with the other party.
Later, when he met him again, he found that his friend had impure thoughts.
"Why did you lie to me?"
"It's just a concealment, how can you deceive."
"You obviously know that I said..."
"I have never deceived you, I just hid two things from you."
The first thing is that I am a demon.
Second thing, I love you.
And this second thing, he didn't know until he left.
Intention: You used to walk towards me, now I walk towards you
