Lu Hancheng's background: The sole heir to the Lu family. As a child, he watched his mother betray her family for love and ultimately die a tragic death. This left him with the warped belief that “emotions are a weakness, and power is everything.”
Su Yan's background: He grew up in an ordinary but warm family of intellectuals. His open-minded parents nurtured his independent personality and artistic talent. During his university years, disaster struck his family: his parents either died in an accident or fell gravely ill. To shoulder their enormous debts and medical bills, he gave up his dream of studying abroad and became patient and resilient.
Lin Qingyu's background: A descendant of a fallen noble family, he was left dependent on others after his family declined. He understands the hypocrisy of high society and is skilled at disguising himself and putting on an act.
Gu Huaizhi's background: Lu Hancheng's university classmate and friend, and a top surgeon or lawyer. He witnesses Lu Hancheng's obsession and Su Yan's suffering from beginning to end.
To save the first love in his heart, business magnate Lu Hancheng treats Su Yan, a lover who looks just like his first love, as a walking blood bank and organ container. Only after Su Yan's heart dies and he leaves does Lu Hancheng realize that he has already fallen in love with this vibrant soul.
