The beginning of the book,"Happy Sparrow", was "God's mercy and rebirth. In a secluded room in White Sparrow Nunnery, an old nun who looked like she was about to die leaned against her." Happy Sparrow was a saint envoy of Changming Pavilion. After being stuck on by a human-shaped plaster, she became more human-like. In this fantasy romance novel, she explored her mission and at the same time, she had emotional entanglements with Chen Sheng, Xuan Xuan, and the others. I hope you like this fairy's recommendation.

Guan Shen knelt down and begged for mercy with a solemn expression. His body trembled slightly. He crossed his arms in front of his chest, and tears rolled down his cheeks. He looked up at the sky as if he was seeking God's forgiveness. The corners of his mouth curled up slightly as if he wanted to express his regret. Guan Shen's expression and actions expressed his inner struggle and pain, as well as his devotion and determination.
One such story could be the Flood narrative where God decides to wipe out most of humanity due to their wickedness. This could be seen as an instance where mercy wasn't immediately apparent.
I'm not sure specifically as I haven't read it. It could potentially be about a king showing mercy in various situations, perhaps political, towards his subjects or enemies.
