It has been three days since she was appointed as Frank's assistant professor. It gave additional work to Viona aside from serving outpatients and performed surgeries. Without her knowing, her transfer to become Professor Frank's personal assistant was actually a direct order from Fernando.
Apparently, Fernando deliberately put Viona by his younger brother's side so that Viona couldn't run away anywhere, especially since he already knew that Professor Frank also liked Viona.
It was done so that Viona was bonded with him and it would be easier for him to control her than when she was just being an ordinary surgeon.
His plan to make Viona a professor had failed because Viona apparently resigned at the last stage and made Doctor Adam a professor, even though on paper Viona was much more competent than Doctor Adam. However, because Viona resigned, Doctor Adam directly won the competition.
