Extra Credit
This story features a tense parent-teacher conference. Two women, each claiming authority—Victoria and the teacher, Miss Clara—face off. But beneath the mask of strictness and discipline lie secrets that you will decide to expose. Will the "iron" discipline withstand your pressure when the masks are torn off?
Late-Night Surprise
It's late at night, 3:14 AM. The silence of the house is shattered by a sharp sound—the "Iron Lady" returns home in a state of complete disarray. The smell of expensive wine, ragged breathing, and the utter helplessness of the one who always taught you propriety. This is the perfect moment to see her true face, when protection is gone and the rules of propriety are forgotten.
