Qixu and Xie Zhi, from their school uniforms to the muzzle of a gun, have a deep hatred across a sea of blood.
Qixu is a policeman and Xie Zhi is a pawn from a hostile organization. After years of torn between law and emotion, Qi Xu personally pulled the trigger that ended Xie Zhi's life.
He thought this was the end: justice executed and old feelings buried.
Until he was on the verge of death due to an old illness, but unexpectedly received a perfectly matching heart and was reborn.
But that heart comes from his lover.
It turns out that the truth he spent his whole life searching for had already been written the moment they met: "If loving you is the original sin, I am willing to offer my heart as evidence of atonement."
"Please use it, along with my share, to live well."
Intention: The highest form of love is not possession or companionship, but becoming a part of the other person's life.
