Princess Zhaoyang Zhao Lingzhao was born in the royal family and received all the honors and favors, but she was tired of the constraints and marriage arrangements in the palace. In the spring of her seventeenth year, she went to the mountains to seek shelter from the rain to pray for blessings, and met the monk Shi Xuanchen by chance at an ancient temple. Xuanchen has a calm temperament and compassion. A few Zen words soothed her depression, and Lingzhao fell in love with her at first sight.
After that, she frequently went to the temple to make tea and talk with Xuanchen. She confided in the palace's oppression, and he enlightened the cause and effect in the world. After being together for a long time, the girl has a deep love; Xuanchen abides by the rules and tries his best to restrain himself, but his ordinary heart is still moved, and he secretly cares about and protects the princess. The two hide their secret love between the royal rules and Buddhist precepts.
This affair was discovered, and rumors spread throughout the capital in an instant. Emperor Long Yan was furious, and the abbot of the temple severely punished Xuan Chen and ordered him to cut off his worldly ties. With pressure from the imperial power on one side and punishment from Buddhism on the other, the two fell into a desperate situation.
Lingzhao refused to compromise and refused to marry in public. She was willing to give up her status as a princess and her wealth, just to stay with Xuanchen. Xuan Chen knew that the entanglement between the two would only make her scolded by the world and fall into endless danger. In order to save her, he chose to endure the pain alone, indifferently denying all affection in public, and cruelly drawing a line with her.
Unable to contend with fate, Lingzhao was eventually forced to go to a foreign country to get married, and stayed alone in the palace of a foreign country, leaving only loneliness for the rest of his life. Xuan Chen practiced hard behind closed doors and became a respected monk. He could enlighten thousands of people in the world, but he could not let go of the obsession in his heart.
The two loved each other and never let each other down, but their identities, etiquette, and destiny stood between them, and they could not stay together after all. The first encounter in a spring rain resulted in a half-life longing for each other. From beginning to end, there was only a regret that could not be fulfilled.
