The second female lead never faces the consequences for what she's done. While the second male lead in dramas is usually perfect in every way, the female second lead is BBFs with Satan, doing horrible things throughout the drama, sometimes even committing CRIMES and at the end they all forgive her. Sometimes she doesn't even say she's sorry, yet everyone is happy to forgive her.
How long people faint for is crazy. If after getting hit in the head you are unconscious for longer than a minute that's almost always some serious brain damage, yet in dramas you're fine. Or if you pass out for any other reason being non responsive for hours after you faint is super dangerous and most definitely a trip to the hospital, yet everyone in dramas is placed in their own bed and wakes up completely fine.
