Judging by the actions of Wu Heng and the other person, it's clear the two are in a romantic relationship, not just a publicly declared business partnership.
A romantic relationship may not be entirely accurate, as Shanaela has a husband and is among the high-ranking members of the Elf Race.
Calling them lovers might be more precise.
"Are you adapting well to life here?" Shanaela asked like a hostess.
"The Leader has been very considerate of me," Viola replied.
"What's your level?"
Viola instinctively glanced at Wu Heng, who showed no sign of stopping her. Viola answered, "Level 19."
Shanaela raised an eyebrow, "Quite fast, keep it up."
"Thank you, Lady," Viola expressed her gratitude.
Shanaela nodded, "You guys go ahead and get busy, I need to discuss some things with Wu Heng."
The others stood up and dispersed to attend to their matters.
Only the two of them were left in the living room.
