Kiro slept like a baby that night. Even though he chose the floor, giving Felix his bed. That's just how he was taught, you treat guests better.
He would've minded if the floor wasn't so soft and comfortable to sleep on though. It had only been a couple of months, but he was too used to his soft beds now. He couldn't even imagine how his previous one felt.
He wasn't going to pry but he guessed why Felix needed time away from the Black estate. Now that he had money, he could afford to buy himself and his father a house. But that would feel like he was leaving Nikolai behind.
That's how deep his loyalty ran.
He also knew that Nikolai wouldn't want to leave the estate, that's where his mother died, that's where she was buried. He wouldn't mind taking him with wherever he wanted to buy the house, but he had every problem with leaving behind with just his father.
