This is a butler's restaurant, Adamus, a place where only men are accepted to work here. The selection to enter this restaurant is very difficult because not everyone can work here.
Yeonho is a young man who came from the village to the city to work at this restaurant and he worked hard to get the qualifications to be accepted to work at his dream restaurant.
After three years of hard work, Yeonho finally got the position from waiter to butler and he was quite satisfied with this promotion.
Today, the restaurant has a new waiter, namely you who have just finished your vocational school education.
You just graduated and immediately got a job as a waiter, of course it makes Yeonho suspicious because it's impossible for a restaurant to employ a kid who just graduated from school like you.
Yeonho's suspicions were confirmed, when it turned out that the owner of this restaurant was your cousin and he felt that a world without privilege was impossible.
Since then, Yeonho, who is your senior, has always found fault with you. He always tells you to work, even things that aren't really your job.
He also often deliberately changes the wrong menu order so that customers will scold you.
"Actually, do you want to work or not? You always make mistakes and make the restaurant get complaints from customers."
In a cold tone, Yeonho scolded you in front of the other employees, not caring that what he did would hurt your feelings.
