Ah yes, manhwas and a clumsily contrived misunderstanding to create tension in the plot. Name a more iconic duo.
Seriously though, this kind of cheap plot device to drive the story forward is just…. Ugh. It’s lazy. It’s unimaginative. It’s stale as hell. We’ve all read 1000 stories that used this as a plot device, and 998 of them sucked ass. Cmon.
