I like this, what a unique female lead, badass too.
And I love the classic dynamic, she is the brains, he is the muscles.
So I read the novel spoilers, and this have far to many cliches for my taste,
1) load and behold this is not a case of reincarnation but regression, the FL has been the original one all along and this is actually the 3rd time line.
2)OGFL have this ability to make everyone love her in abnormal levels, basically brainwashing them.
3)the OGFL at the end turn to a demon by the evil god who give her that power and is killed in her last moments she reflects and said that in the end, in all her life times no one really loved her.
You know, it is genuinely nice that the second guy, isn’t a second male lead, instead just a friend who genuinely wants to save her because he genuinely cares about her, not just because he is in love with her.
