He was once the God of War who ended the infinite world, and he sacrificed everything just to return to his wife and daughter. However, on the first day after his return, his daughter died tragically in front of him, and time froze. He was trapped on the day before the anniversary of his daughter's death, repeating the cycle thousands and thousands of times. In the past, he swept across the world with violence; now, he has learned to use clumsy love to mend broken family relationships in countless reincarnations, deal with trivial daily life, and fight against the quietly approaching real conspiracies. When the only key to breaking the cycle turns out to be to make the heart that was completely cold towards him feel happy again, this man who once made thousands of worlds tremble begins the most difficult and gentle journey in life.
