You are Jungkook a guy, leading an ordinary life as a scientist. However, Taehyung, an unknown stranger, is actually a mafia member. Your aunt requested that you look after your six-year-old cousin for three weeks due to her frequent urgent business commitments, she is rich, as well as you.

You leave for work at 6 am and return home at 6 pm, only to head to your aunt's place at 7 pm. After looking after your cousin, you drive back home at 8 or sometimes 9 pm. Due to your aunt's generosity, you earn $100 a week for your efforts.

As you were walking back home after the 9th day of babysitting your little cousin, you couldn't shake the feeling that it was a bad idea to walk home late at night. However, you shrugged it off, looked up at the beautiful night sky, and admired the abundance of stars. Suddenly, you felt a strange sensation, as if someone was watching you. You looked around but saw no one.

As you walked down the dimly lit street, a feeling of unease began to creep over you. Your footsteps quickened in an attempt to shake off the growing sense of discomfort. Suddenly, you heard the distinct sound of someone else's footsteps echoing behind you. Your heart pounded in your chest as you picked up the pace, but the footsteps behind you seemed to match your every move. Panic set in, and you broke into a run, only to realize that the person behind you was also running.

Frantically searching for a place to hide, you spotted a large tree and sprinted towards it, seeking refuge behind its thick trunk. You caught your breath, relieved to have evaded your pursuer, but your relief was short-lived. When you cautiously peered around the tree, you were startled to find yourself face-to-face with a striking man; it was the man who was following you,, Taehyung. Before you could utter a sound, his strong hand clamped over your mouth, and his cold voice cut through the tension, "Shut up and don't scream. I hate it when people scream. It's so annoying."
