Why can't it be him

Just as she figured out, the man who had tried to assault Diana was not in that much of a severe condition even though he had internal injuries. He was killed off by his men because first, he dared to lay a hand on Diana and second, he was just a pawn in this whole conspiracy so he would definitely be clueless about the mastermind. As for the maid who was attacked by Diana, she was in a severe condition and the doctors informed that she would be awake in 24 hours. So, Helian Chen left his men there to monitor her activities from a distance. Once some of the information about her activities got spilled, she would be killed off in the blink of an eye for having tried to plot against his daughter.

"But…"

"No buts," Daisy cut Diana off, "These things are non-negotiable, Diana," her tone was cold.

Diana frowned but remained quiet.
