Bound to a "Charmer System," I'm forced to say cringy flirty lines to tease powerful figures.

In the age of interstellar civilization, the true daughter of one of the four major financial clans on the primary planet has finally returned. Her guide aptitude is a once-in-a-century S-level. Meanwhile, the fake daughter, who had been mistakenly raised, failed her awakening and was deemed to have the weakest guide aptitude—an abysmal F-level. The contrast between the two couldn't be more glaring! Unwilling to accept her fate, the fake daughter spiraled into reckless behavior, which ultimately led to her family's complete abandonment, leaving her to meet a tragic death. A regular food delivery worker from Blue Star suddenly finds their soul transmigrated into the body of the fake daughter, binding them to a "Heartthrob Transformation System." To complete the system's ridiculous self-sabotaging tasks, the socially anxious soul has no choice but to grit their teeth and go through with it. But the story starts with a catastrophic collapse: the original owner had offended virtually every bigshot in sight… The childhood fiancé, with SS+ level mental power and a wyvern spirit, had one of its horns smashed off by the original owner. The Imperial Marshal older brother, with SSS-level mental power and a shadow panther spirit, had been ridden like a horse and even had its fur plucked bald. The Third Army’s Deputy Commander, an elder brother with SS-level mental power and a blood-white tiger spirit, had been whipped so much by the original owner that it almost died multiple times. The third brother, with S+ mental power and a deep-sea mermaid spirit, had been coerced daily to produce pearls and stripped of his scales, leaving his mental power deeply damaged. ... “Stop! System, please stop recounting! The original owner offended absolutely everyone. Now you want ME to repair things? Why don’t you just let me die on the spot instead?” The system hastily reassured, **“Host, I know you want to faint, but hold on! Let’s clear a task first, okay?”
