When he was in high school, Lu Shangting hid Lin Xiyan in his heart, like a tide that never receded day after day.
Due to brotherly affection, he could only watch her become the girlfriend of his good brother Gu Cheng.
After spending several years dormant overseas, he founded the jewelry brand "Tide" upon his return, turning the words in her name into a secret known throughout the city.
The elders of the Gu family obstructed the relationship in every possible way, and her boyfriend Gu Cheng was a philanderer. The accumulated disappointment finally made Lin Xiyan choose to leave.
Just when she was wondering about the hidden meaning of the word "tide" and questioned Lu Shangting face to face, the man took off all the pretense of alienation and spread the love he had hidden throughout his youth in front of her.
"From a long time ago, my tide has only risen and fallen for you."
