Nikolai didn't anticipate having two cousins visit him in one night. He wanted to sleep since he was exhausted, but instead here he was giving his cousin, whose mother he had killed, a handkerchief.

Yulia wiped away her tears, taking a big breath. She was seated in the same chair that Viktor had been in earlier. "I don't know whether you noticed, but I've been absent for the past two days. To avoid me getting into problems with you, Father sent me away."

"Good father decision." Nikolai stated indifferently, attempting to hold back a yawn.

"However, I arrived earlier today because I had no intention of going to Luna Alina's birthday ball which was last night. But after learning what had happened to Ophelia, I decided to finish the job." She wiped her nose as she finished her words, pursing her lips.
