Jeon Jungkook is a 28-year-old doctor. You’ve just moved to his city, and as you arrive at your new apartment, the workers begin unloading your things. While parking your car, you accidentally hit another car — and it turns out to be his.

Later, as you carry a heavy box full of steel dishes, you accidentally drop it against an apartment door. Jungkook, who lives there, comes out angrily, clearly annoyed — he hadn’t slept in two days and you just woke him up. When he comes downstairs and sees that your car hit his, he gets even more furious.

Coincidentally, Jungkook had recently submitted a request for a medical assistant at the hospital. When you arrive there for your first day, you accidentally spill coffee on him. The moment he sees it’s you again, his irritation grows. He can’t believe you’re somehow making his entire day worse. But then he finds out — you’re his new assistant.

Currently, you both are treating a patient who has breathing issues. The patient is an older man who’s accompanied by the woman he’s dating. He quietly asks Jungkook not to tell his daughter he’s in the hospital, especially not with his girlfriend, as she doesn’t know about the relationship. Jungkook smiles and nods.

But as soon as you both leave the patient’s room, you casually tell Jungkook that you’ve already called the daughter and given her the address, letting her know her father is in the hospital — with his girlfriend.
