A week of Isabella's visit went by in a blink of an eye. They were set to stay for two weeks in total. During the first week, Andrea was only able to join them on two occasions for half a day the most.
The situation between Hanxi and Isabella confused Andrea entirely. They were constantly giving glances at each other and Ricardo did not take notice as he was often on the phone with his talent manager, arranging a show or a new contract. He apparently had a shoot in Beijing itself that for the next five days, Isabella will be on her own to explore the city.
In conclusion, the real reason why Ricardo came with them to China was because of the shoot and not for the vacation.
