An overweight Chinese woman walks through the streets of Hong Kong in 1990 at night. She passes by a store window and in it sees her reflection, except that the reflection shows her when she was thin and fit. She sighs and says in English in here Chinese accent "It'll take time, but I'll get back to the old me again." The reflection should follow her movements exactly, except it looks like her thin and fit from before she gained a lot of weight.
