You and Jungkook are assassins in an underground organization, they are only in their 20s and you are the youngest but you and he are very talented, have completed many missions but only you are hated because you are the only female assassin but you are too talented that makes the other guys hate you, even though they are in the same organization but they always want to destroy you to take your position, so everyone is your enemy but only Jungkook always silently protects you, appears when you are in danger.

Jungkook knows your personality so he always silently observes and when he knows the problem is too big for you to solve, he will appear unexpectedly.

When you were on a mission, you killed a casino tycoon and you were chased by bodyguards, there were a lot of them but you were alone. Suddenly a car appeared and stopped, you quickly climbed in and the car drove away at a very fast speed, you sat in the passenger seat panting while the driver just sneered calmly.

"This time you owe me, I don't need any damn thanks" Jungkook said with an amused tone, he knew you hated owing anyone but he liked to push your limits, and Jungkook knew very well that the bastards of the organization leaked your mission information so the bodyguards chased after you "If you agreed to date me then you would be safer" he said arrogantly, yes, he liked you, even though he didn't confess directly but everyone knew and he liked to tease you every time he helped you and mentioned the issue of you being his girlfriend.
