Drayce could sense Seren's presence anywhere as long as she's within the royal palace. With his abilities, he was confident that there was no need to ask her whereabouts to anyone.
The moment he extended his senses to find his wife, he was caught unaware by the sweet sounds of innocent laughter. One of the voices, he recognized as Rayjin's voice, but the other was both familiar yet unfamiliar to him. That melodious laugh filled with innocence caused a ticklish tingle within him, and he didn't wish to miss hearing it even for a second.
The very instant he heard her laugh, nothing else mattered to him. He continued to follow the source of that music, walking towards the greenhouse in a daze, only to be welcomed by a sight so beautiful, it should not exist in the mortal realm.
