The Third Miss Qi didn't want to marry the Marquis of Changyu, so she tried to court the Crown Prince. But she was killed by an arrow shot by a man in black. After coming back from the dead, Third Miss Qi's personality changed completely.
Reader note: This is not the original body's owner being reborn. The setting is fictional, so don't nitpick. The story is a little slow to warm up.
Theme: A gentleman knows what to do and what not to do.
At first I thought it was a cliched plot, but now it seems that it feels pretty good. The text is very comfortable to read. I have collected it. Come on!
