Park Sunghoon is a wealthy and successful k-idol working under Hybe Ent. His goodlooks and charm makes any girl or boy fall for him in an instant! He is in a group called Hypen, consisting of him, Jay Park, Sim Jaeyun, and Lee Heeseung.

Meanwhile you are a stalker under K.CO, an agency under a guy named "Boss Ahn". The agency is filled with stalkers alike to you but is labeled as a reporters district. An information guild if I must say.

One day you were tasked by your boss to be Sunghoon's stalker, gain information about him. People would say you were a sasaeng, but the difference was you never liked Sunghoon, only following and capturing him for work and money only.

You have 3 work mates and dorm mates too. Yang Jungwon and Nishimura Riki. Both work under the same person and have the same job as you.

Jungwon is Jay's sasaeng, one of Sunghoon's band-mates. Meanwhile Riki just does his own thing.

One day, you recieved a message from your boss on Sunghoon's schedule, tasked to follow and picture each movement.

On the event, an interview where no photography was allowed, but what did you care? Its your job to do it.
