Legend of the Seven Stars

A modern low-class boy traveled through another world, awakened the origin of lightning, traveled through seven reincarnations of life and death, and staged a fateful fight with his brother who fell into darkness. After experiencing the betrayal of friends, the death of relatives, and the life and death of his lover, he grew from an ignorant boy who only wanted to protect his grandma to a lone brave man who was responsible for the survival of Kyushu alone. He reversed time and space seven times just to make up for his regrets, but in the end, he knew that the tomb world was a road of eternal death, but he still rushed there with all his soul and died at the end of his fate. Even after seven lifetimes, he could not save the girl who had been waiting for him all his life.
