Klaus spent a few minutes chatting with Hanna. When midnight came, he asked if he could stay the night with her. Hanna didn't mind at all. They were siblings now, and despite Klaus's reputation for being shameless, she instinctively knew he wouldn't do anything inappropriate.
She couldn't explain why she felt so certain, but the way Klaus looked at her told her everything. There was no hint of bad intentions in his eyes. Their mother had even reassured her, saying she didn't need to worry about Klaus. He wasn't the type to cross that line with her.
In truth, Klaus's past—his life as Fruity—made him extra protective of Hanna. He carried memories of the time they had spent together, the love and care she had shown him, and the ultimate sacrifice she had made for him and his in the end.
