This is a love song about extreme burning and complete death.
Lin Chen, who was once the proud son of heaven, spent all his youthful flames in love with a girl named Su Qing. But her realistic choice caused him to fall into a silent abyss, suffer from aphasia, and become a "monthly ghost" who numbed his pain by dating constantly. He hurt countless people, including himself. Many years later, she shed tears of regret in the golden siege, begging for a chance to turn back, but he coldly refused, choosing to go far away and reconcile with herself in loneliness.
She enjoyed all the prosperity in the world, but she lost forever the only person who was willing to devote his entire soul to her. Missing something is a lifetime.
Concept: True love is respect for your lover, unfeeling is respect for yourself
