He Knew

Yohana's chamber was a considerable distance away from Henrie's, making it impossible to inform him of her nighttime plans. In truth, this arrangement was probably for the best. Yohana wasn't sure how he would react if he knew she was about to visit Fabian. 

In Henrie's eyes, Fabian was a potential rival for Yohana's affections, completely unaware of the complex truth - that Fabian was his own crush's brother. Given the circumstances, Yohana felt it was only fair to keep him in the dark for now.

She donned her hooded coat, ready for her clandestine venture. Thea had arranged for a waiting carriage outside the imperial palace, which would transport her to Fabian's residence. 

Meanwhile, Thea would ensure that no one entered Yohana's room or inquired about her whereabouts. If any questions arose, she would impersonate Yohana, pretending to be asleep.

The journey from the imperial palace to Fabian's residence proved to be a brief one.
