By the end of the week, Bai Jingye left with Lu Mengjie for Switzerland bringing no one with them. No one but them. It was so they could escape from the eyes that monitored their every move.
At first, when Bai Keran learned of this from Steward Fang that they didn't want to bring anyone with them, he tried to change the couple's minds but failed to do so since they were using the 'honeymoon' as their reason. The elder wasn't able to do anything... or so they thought.
Bai Jingye knew that his grandfather wouldn't just sit still without doing something so he was already expecting that sick old man was going to send someone to keep an eye on them. The 'married' couple already anticipated such actions on Bai Keran's part, that was why upon arriving at the foreign country, they were careful with how they acted.
