I fucking wasted 78 chapters for this incest shit this is why I can never trust straight manhwas
Incest is blood relation. They were raised together but not related at all. There were no romantic feelings until years later when they were both adults.
I sincerely hope you don't have siblings
im not religious but thank you god for creating the universe, so that the earth would birth humans after billions of years, so that humans could produce electronic devices, so that this breathtaking manhwa could have been read by me today. countless coincidences accumulated that led up to me reading yaoi, such that it can even be called destiny.
came here after chapter 3 to say WHAT THE FUCKKK I GENUINELY THOUGHT HE WAS JERKING IT WHY IS HECUTTING NOOOO
