Stepsiblings. 0-0

Wtf is up with manhwa characters making out with their step siblings, I know they aren’t related by blood but they’re still SIBLINGS!! Like I’ve still read some but like, COME ON!!! Am I the only one who tries not to think about the incestual undertones??
“Dear Manhwa Writers:
You don’t have to make them siblings.
