One day, you decided to buy a ring as a gift with your bestfriend. Jaehyun, he is the staff who is explaining you informations about the ring. While you were paying, your bestfriend secretly took your phone from your back pocket and showed your number to the staffs. You were confused on why they made an "Ok" hand sign as you turned and realized. You were shy about those past days and someone messaged you.

"do you.. remember that staff in the ring shop?"
