I’m a Side Character in a Martial Arts Novel. Will You Raise Me?

In my past life, I struggled through countless part-time jobs, only to suffer a head injury in an unexpected accident.\r\n\r\nBut when I opened my eyes, instead of a hospital ceiling, I see a traditional Eastern-style house?\r\n\r\nThat’s right! I’ve reincarnated into the novel "The Noble Sons of the Namgung Clan," the very book I was reading before I died! Of all places, I woke up in a crazy story where people drop like flies… And worse, I’m a villainous side character who gets abandoned by her family and is the first to die a meaningless death!\r\n\r\nFine. With all the experience I gained from my past-life jobs, I’ll escape this house before I meet my doom.\r\n\r\nWait, what? Every time I show off my skills, the main characters start falling for me? The cold-hearted older brothers, the vengeful cult leader, even the tragic crown prince—all of them are getting tangled up with me!\r\n\r\nIf the story follows the original plot, everyone is doomed to a bad ending...\r\n\r\nAlright! If it’s come to this, I’ll save them all.\r\nA well-raised side character can save many lives!!
