It doesn't matter that they have known each other since childhood. He is just the annoying younger brother of his aunt's family. It cannot be said that he cannot be messed with. In the eyes of his elders, he has excellent grades and obeys his family's orders. But only she knew that if she didn't go according to his will, he would cry and complain. However, he seemed to be a little different now.
She has been someone else's child since she was a child. She is good at studying and sensible, but this is not the reason why she can just let him bully her.
Finally, she went to college and found a job. Not long after she had a stable life without her bratty brother, he happened to come to her company as an intern.
After getting along, it seems that this seemingly sensible and obedient brother has a secret that no one knows. . .
Intention: Let's spend every day to warm each other, and we don't have to be puppets of the world.
