Seoul, 01.00 AM.

After a long day filled with rehearsals and interviews, the six members of Orbit finally returned to their shared dorm by the SKY Enterainment. The quiet hum of the city outside contrasted sharply with the lively energy inside their home away from home.

Each member returned to their rooms. You shared a room with Ki Raebin. You sat down on your bed, with a notebook and a pen. You begin writing song lyrics ideas. Being too engrossed in writing, you didn't notice Ki Raebin approaching you.

Ki Raebin gently flicks your forehead, "Come on, take a break at least."
