This is a very old-school kind of story, featuring a woman who transmigrates and plenty of male candidates. It has Mary Sue tropes, melodrama, physical and emotional angst... and a return home.
Male A: Maybe a good guy?
Male B: Bad guy!
Male C: A plant.
Male D: Just passing through.
This novel is also known as "Su He's Adventures."
Other details: The heroine transmigrates more than once. Among the four male supporting characters, one is a villain, one is a fellow transmigrator from her hometown, one is her destined match, and one dies at the end.
Match the clues. Guess who the male lead is.
