This is time travel.
He traveled to a strange era and discovered that the former owner of his body was just the tragic result of his father's love entanglement.

Someone wanted to kill him, but he soon gave him tender hope.
Where can he find his peaceful haven like home?
He can only rely on his own efforts,
Write your own glory on this land.
