It is a sweet burden of hope and destruction.
Shrouded in the shadow of the collapse, the surviving people built a fortress called the "Fire Chasing Moth" to fight against the doomsday with tenacity. Young Cheng, this child miraculously held in his arms, should have had the most stable childhood under the care of two strong men.
However, cracks were carved in the script of fate as early as the beginning. When his body becomes the resonance source of the harbinger of the end, sweet celebration and bloody resolution come on the same day. The choice between love and survival pushes the closest people to an unsolvable desperate situation.
This is a swan song about secrets, protection and sacrifice. How can a young man choose to let go quietly in the ultimate happiness and use his own way to carve a way out for the one he loves? This is not only the end of a battle, but also a journey of how the soul completes its final burning in the ashes.
