Mi abuelo de 10 años es un genio

Ethan, the world champion of Go, met two gods on hills. They were playing chess. After taking over one round of the game for a god, 49 years had passed on Earth. They gifted him a Divine Peach, which turned him into a ten-year-old boy. Ethan returned home as a child, but was blocked by bodyguards, bullied by his grandson, and despised by his son-in-law. He solved the Exquisite Go Game to prove his identity and used the peach pit to wake up his wife. But there was another hidden story behind the family crisis.
