She has a good personality, is popular, and has a lot of money: Gu Do-Yeon, the daughter of the perfect G company president. However, Do-Yeon's step-sister Gu Yi-Seo is just unlucky and annoying.

(Lezhin, translated) 

Note: 
- Chapter count includes a prologue. 
- Part of Lezhin's Gwanggong Collection (광공단편선). A gwanggong (광공, hanja: 狂攻) character is obsessed with the object of their desire, similar to the Japanese "yandere". Scanlations have erroneously translated this to "GwangGong Apartment/Industrial Complex", which may have caused confusion.
