Gone crazy

"I think I just broke my heart..."

 Luna saw Kevin step up after saying such ambiguous things.

 What does it mean? Did he just break his heart because of me?

 Luna wondered in her heart, she then walked to follow Kevin's steps even though she was still one step behind Kevin. They didn't speak at all until they finally entered the elevator.

 "You don't want to come in?" Luna asked several employees who were still standing in front of the open elevator door without entering it, but because there was no answer, Luna finally closed the elevator door tightly.

 Luna feels that the attitude of the company employees is hostile to her but she can't remember when she made a mistake and she always tries to be friendly but after returning to work she feels like an enemy to everyone.
