So he stopped following Kate and went to the kitchen instead.
He grabbed a kitchen knife and shouted, "KATHERINE!"
Kate turned around spontaneously and gasped when she saw Henry with a kitchen knife. His eyes were devoid of emotion.
Henry aimed the kitchen knife to his throat and said, "I am serious, Katherine. I truly love you. I am hopelessly, ardently in love with you. That's why I abandoned all of my old schemes, and inheritance for you."
"I start anew to give you and our baby the freedom you deserve. I want to have a family with you…"
"You… you are my one and only, and if you leave, then there is no point in living anymore," Henry said. He began pressing the tip of the knife to his throat until a drop of blood leaked out.
Strangely, he didn't feel pain at all.
He was just happy because Kate finally listened to him.
So if his death was the way for her to listen, then so be it.
