The Baengri Clan's Unwanted Granddaughter

Yeon was just an orphan on the streets when a man claiming to be her father brought her to his family home. But the Baengri estate was a den of vipers that swallowed her whole, and it's only when she's standing at the funeral of the father she never truly understood that she realizes how familiar this story is. When she wakes up six years old again, Yeon knows she can't waste her second chance. This time, she's going to save her father. This time, she's going to live without regrets. --- Here, inside this martial arts novel, there is a true teacher who teaches the arrogant male lead and awakens him through death. Handsome, good-natured, righteous, strong, and… Anyway, there was one big flaw in the male lead's damn fine teacher. It was his foolish only daughter who was filled with greed. A tenacious villainous extra, who always comes back to haunt the male lead in every way, but cannot be abandoned because she is his teacher's daughter. Throughout reading the novel, I cursed at that daughter. Saying that if it were me, I wouldn't live like that. 'But that didn't mean that I wanted to be her!' What was worse, Father has already died, and my reputation was the worst. Inevitably, I ran away, but… I died. However, when I opened my eyes, Father was alive?! 'If so, in this life, I will definitely save Father!' However… "To think they’re aiming for my granddaughter?! I'll kill them all!" Why do I see Grandfather, who doesn't even appear many times throughout the novel, so often like this? "Marriage? No. Yeonie said that she would live by my side for the rest of her life." Even Father, somehow became weird. Moreover: "Why do you keep avoiding me? Is this also my mistake?" Isn't the main character suddenly becoming obsessed with me? "Originally, I was destined to die. Until you came here." I saved the time-limited bastard, but isn’t it that no good deed goes unpunished? "At least when I'm in front of you… I don't think I’m trash." The villain who blew off my neck is suddenly trying to repent. Is it really okay if it's like this?
