A common trope (if we can call it that) in #Kdrama is they always tell their plans/next step to their enemy/opposition, otherwise, there won't be friction and twists. ^_^;;
E.g. “I'll talk to B tomorrow, so forget your plans.” Which won't happen because of the tip. LOL
@youronlyone A common variant is when they unintentionally tell the enemy their plans by lengthy, detailed conversations carried on in public or near public spaces at significant volume
