彩虹
She should has a boyfriend/customer/relative living in my building. Always see her taking our lift in the morning of Fri and Sat to leave our building. Once saw her entering the building with a guy on Fri night. Everytime, she carrys a very big Gucci bag (likes bringing many things for use overnight) and wears low-cut and short-dress/skirt (even in cold cold winter).
I saw her leave the est. via car park by herself once even she is under 18 years old and should not have a car. Maybe she doesn't want ppl seeing her.
