The Sacred Serpent's Seduction

How far would you be willing to go to save the ones you love? With his grandfather bordering life and death, Tae-Sun takes on multiple jobs in order to pay a seemingly endless stack of hospital bills. On one of his odd jobs, he ascends the great mountain Geumryang, unknowingly the home of an eponymous serpentine spirit. When Tae-Sun encounters the divine being, he too is on the brink of death, desperate for water in his slithering form. Tae-Sun offers him a sip of water, and saves the sacred snake from certain death.

After all, can one ever truly trust the forked tongue of a serpent…? (Source: Lezhin US) Note: Includes 22 extra chapters.
