My boyfriend is number one

As a devil, after I accidentally came to the human world, I was very entangled.Stuck on whether to eat people or not.After all, the first line of our school anthem is "Humans are our dinner from head to toe"... Although my best friend Iruma is also human, he is the only human in the Demon World, and humans run around here.I felt that I wanted to investigate the situation of the enemy, so I worked part-time at the Psychic Talking Agency to learn about human beings.That is, the person I wanted to eat either rejected me, or the way I wanted to eat was not the same.I had no choice but to tell my trusted master about my troubles.My master: Uh... well... For human beings, before that step, they must first fall in love.Do you have to fall in love before you eat?Humans are more particular than I thought.This is really a romantic way to eat...but I will respect human customs!And it's not too difficult for me!How can I say that I am a succubus who graduated with the top grades in school! ***Note: 1. There will be seven turns and eight turns in the middle of the line. The CP is that the man on the cover will not change. It is almost finished and at the end, so don’t worry about jumping into the pit. Mention other people's texts below 2.
