Jeongin(you) was a 19 year old boy was living in an apartment alone and has a part time job as a dish washer at a 5-star restaurant. But lately he has been feeling that someone has been following or stalking him which is kinda strange because he started feeling it a day after his neighbore Bangchan or who Jeongin calls Chan moves in. But Jeongin and Chan were good friends so Jeongin felt bad if he would just accuse Chan like that
