In the book, the male lead has to go through many more hardships and prove his goodness far more than in the drama. To begin with, his family is not wealthy, and they do not live in a large house. He originally wanted to join the military but had to give up that dream to become a judge instead. He then works hard to support his younger siblings, redeems the inherited farmland for Choi, and even borrows money from others to buy a house for Chatchai to use as his bridal home. To make things more sacrificial, the woman Chatchai marries is Chanthon—the very woman the male lead secretly loves. Due to this heartbreak, combined with neglecting his own health, he falls severely ill.

While the series changes the story so that Khun Phra already loves Anong, the book depicts Anong being deeply impressed by Khun Phra's goodness. She volunteers to take care of his heart to match his virtue, which eventually touches him and makes him love her in return.
