During the decisive battle between the leader of the righteous path, Yu Qinghuan, and the Demon Lord Shen Yunxian, he mistakenly touched the ancient forbidden magic and changed his body every three days.
In order to cover up the public's eyes, the incompatible two were forced to live together and staged a ridiculous farce in each other's identities: she used his body to recite the "Pure Heart Mantra" to cause the demonic energy to be disordered, and he used her celestial appearance to eat spicy food and dance to destroy his image. At night while sleeping on the same bed, temptations and confrontations lurked. The words "It's my fault that your body is sensitive" were all taboos.
As the number of body changes increased, they got a glimpse of each other's unknown scars - the old scars on her shoulders hid the courage of a young man, and the crescent marks on his waist engraved the past of abandonment. When the shadow clan behind the scenes uses forbidden magic to disrupt the three realms, the opposing stances of immortals and demons collide fiercely with the quietly growing emotions. From scheming against each other to fighting the enemy side by side, from kissing souls to breaking the curse together, they finally understood in life and death: the so-called righteous path and the evil path are not as good as the shared heartbeat when changing bodies, let alone the words "I choose you" hidden between the lips and teeth.
