Are they blood-related?
Nope they don’t share blood they just grew up together
Actually in manhwas, u can't write stories with blood-related relationships bc korea doesn't allow it, it's always step siblings/dad-son, and that's a thing alot of ppl don't know it

Author me × daddy shared with us her story as an example
Seeing ppl here crying over incest manhwa being incest is something, like do yall hate the fact that incest manhwa actually reminds u that it's incest? Is that like make u feel more guilty or bad to read? Ur reading incest manhwa regardless if it was mention once or twice, it won't change later too
