(The protagonist is not a transmigrator, just an ordinary person.)
Su Yu is one of countless ordinary people in the nation of Liyue. If not for the upheaval when he was ten, he would likely have inherited the family business as a matter of course, then married his childhood friend, Keqing, just as naturally.
But after that rainy night, all of it turned to ashes.
From then on, he left Liyue and went to Mondstadt to lie low and bide his time.
And just when everyone thought the former eldest young master of the Su family was dead, he quietly returned.
(Revenge + Keqing as the sole female lead + the story isn’t limited to Teyvat and will incorporate some elements from ancient China.)
(Some place names may be slightly adjusted to better fit the story. The seven nations will also be made more powerful, and some original locations will appear.)
