In the apocalyptic ruins, a mechanical heart learns to beat for humans.
Cheng Yuan × Ji Han
"They said I have no heart, but after meeting you, my mechanical heart started malfunctioning."
——
In the seventh year after the world collapsed, Ji Han discovered Cheng Yuan in the training cabin.
As the first-generation experimental subject of the "New Humanity Project", what beats in Ji Han's chest is a cold mechanical heart. He has no memory, no emotions, and is the perfect killing machine. Until he met Cheng Yu'an, a young man who had been frozen seven years ago in an abandoned laboratory, the man who had secretly stuffed him with chocolate but was forgotten by his own hands.
Cheng Yuan remembers everything. I remember Ji Han wrapping him up in the rain with his coat, remembering the console that Ji Han smashed when he was forced to cleanse his memory, and even remembering that the blood flowing in his body is the key to maintaining the operation of Ji Han's mechanical heart.
"I'll teach you this time." Cheng Yu'an pressed his trembling hand on Ji Han's left chest, "This is missing, this is pain, this is... Love."
When acid rain began to corrode the world, and when Ji Han's mechanical heart entered a 72-hour countdown, Cheng Yu'an smiled and started the self-dissolution process.
"Put me into your heart. From now on, every time your heart beats, I am saying I love you."
Purpose: Love and Peace
