The Supporting Female Lead Refuses to Be a Cannon Fodder After The 1970s

Two powerful leads. The woman uses the man.

Content warning: The female lead smokes and is highly skilled in combat. She's the kind who fights the male lead head-on.

Note:

1. The female lead isn't a virgin, while the male lead is. She thinks this is her second life, but she was actually reborn for the third time.

2. Fictional setting. This isn't for readers who demand historical accuracy. Just assume it's an alternate world. There's a very one-sided crush, and the couple won't be broken up.

Theme: Love is an obsession, powerful enough to bind someone for all eternity.
