The expression on Ren's face didn't change. He remembered Vega working for RMI after leaving him and even coming with her co-workers to the new year's party held by the palace.
He could imagine that Vega's co-workers might be confused and were all guessing what really happened between Vega and Prince Renald Hanenberg, after all the photos were leaked to the media.
Of course, they would try to guess when exactly Vega and Ren started meeting and get connected. Most likely, they would guess that the meeting of the two took place for the first time at the royal gala, considering that Ren asked Vega to dance and then carried her away when she passed out in the ballroom.
After that, Vega disappeared and never returned to work. She even tendered her resignation to Mischa over the phone. Vega never contacted the office to tell them how she was doing and what had happened to her.
