[This section is in Kane's POV]
After seeing Leo and Hunter off, Kane's expression changed immediately. His original pleasant and nonchalant smile was replaced with a look of slight annoyance and irritation. Furrowing his brows, he couldn't help but mutter, "I really underestimated how chummy their relationship are at this stage. I had thought that with Hunter's psychological problems and past, there would be more barriers between their relationship..."
As his mind continued to spin, Kane subconsciously walked back towards the master bedroom before heading down the stairs that were half-hidden in the corner. After scanning both his eye and thumb and also keying in the passcode, he turned the massive wheel place at the very center of the door. After an unlocking sound, the door automatically moved inwards, allowing for Kane to walk inside.
