Fifteen years after the end of the world, Chalk City is one of humanity's last refuges.
Lin Yu is the strongest swordsman in the scavenging team. He is cold and taciturn, and all his tenderness is hidden in silence. Su Chi is the steadiest hand at the medical station. He is cheerful and tenacious, and all his heartbeats are buried under his smile. They lost their parents when they were young and depended on each other for life. They were each other's only relatives and each other's deepest secret.
Buddy and sweethearts, two-way secret love. One is afraid that after confessing his love, he will not be able to make friends with his family, and the other is afraid of adding a burden to the other person in this precarious world. The Bone Eroder Tide, the Gray-Eyed Bandits, and the Beiling Warlords, when disasters approached Chalk City again and again, they moved from protecting and relying on each other to working together and delivering. At the critical moment of life and death, Lin Yu protected Su Chi with his life, and Su Chi blocked the knife that stabbed Lin Yu with his flesh and blood.
"You're hurt, and I'm even more hurt."
"We must die together."
When the smoke cleared, they finally built their own home in front of the window with blooming sunflowers and raised a cat named Hanamaki.
In the wasteland, love is the only refuge.
There are windows, there are flowers, there are you. HE.
Intention: The end of the world can destroy the world, but it cannot destroy the spring planted by two hearts on the ruins.
