- 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.
