The ordinary male protagonist in this world is busy with life, and he has long given up chasing the goddess of the past. However, the two families are family friends, so they have to handle this relationship with caution.
The heroine of a distant era, burdened with the mission of her family and worried about the future of her country, must use her thin back to carry the tower of tranquility that suppresses the demons.
Two seemingly unrelated people met in the same world by chance. It's hard to tell whether this was God's will to save each other or a revelation of impending doom...
Intention: Life after time travel may not be as easy as imagined.
