[GwangGong Apartment Complex] Weakness

Gu Do-Yeon appears to have it all. As the daughter of the president of the prestigious G Company, she is wealthy, universally well-liked, and known for her genuinely kind personality. To the outside world, she is the picture of perfection. However, her stepsister, Gu Yi-Seo, views things quite differently. Plagued by constant misfortune and finding Do-Yeon’s flawless image deeply irritating, Yi-Seo refuses to believe that anyone could truly be without fault. Driven by resentment and a desperate need to prove her point, she becomes determined to expose the cracks in her stepsister’s immaculate facade. Convinced that no one is truly perfect, Yi-Seo decides to take matters into her own hands. She begins secretly lurking around the company offices, quietly searching for any hidden vulnerabilities or damaging secrets that could bring Do-Yeon down a peg. Her relentless snooping eventually leads her to hide away inside an office, where she hopes to finally uncover the truth. Instead of the scandalous flaw she anticipated, Yi-Seo stumbles upon something far more unexpected—a side of Gu Do-Yeon that completely shatters everything she thought she knew about her seemingly perfect stepsister.
