I've found it

"Will you become a monster or a divine spirit... that depends on your choices." A deep and rugged spiritual mountain. From within it, a heartbeat that had lain dormant for thousands of years breaks through the earth and echoes forth. The imperfect spirit 'Mountain Ginseng,' born from the mountain's spiritual energy and ominous aura, one day encounters a young man named 'Chorok-hae,' who is being pursued by assassins. The heir of an esteemed family, 'Chorok-hae,' asks the 'Mountain Ginseng,' who saved his life, to save his dying father. "Tell me everything you know. Then I shall gladly save your father." Can the 'Mountain Ginseng' come to understand humanity and become a complete divine spirit through his journey with 'Chorok-hae'?
