But Ling Chen mistakenly thought that changing his surname was a malicious taunt, and the two fell into an endless tug of war. Ling Ying's gentle confinement repeatedly destroyed Lin Chen's hope of survival, and Chen Chen, who was desperate, finally threw himself into the sea and died.
The two have been entangled for half their lives, hurting each other, redeeming each other, and destroying each other. It begins in the deep sea and ends in the deep sea. This is a tragedy that no one can win and that will never be solved.
