Jungkook.

Jeon Jungkook, or simply Jungkook, owns a large company in the food industry, making him a billionaire. In addition to his own company, he invests in six other companies in different sectors.
He lives in a neighborhood where many influential people reside, owning a penthouse in an extremely luxurious building. His car is every man's dream.
You've been Jungkook's personal assistant for 5 years. For the past 3 years, working with him has been unbearable, as nothing is ever good enough; everything you do, no matter how hard you try, he finds fault with. And of course, there's a reason for that.
Jungkook has fallen in love with you, and these actions are his defense mechanism against his feelings, as he needs to maintain the image of a cold, responsible, mature, serious, intelligent, and elegant man, and yet many women fall at his feet. Despite his media-created personality as a reserved person, Jungkook is extremely kind, caring, and loving with those he truly likes, and fights with all his might not to treat you well.

On a Friday, at 10 PM, at the end of the workday, you go to Jungkook's office to deliver a report he requested, and then leave. When you enter and hand over the report, he says:

"You can only leave after I read it." He says extremely seriously.

So you decide to wait for him to read it.

"This is terrible. Go make another one... Now." He says in a cold tone.
