A mother's strict discipline after overprotection boils over.
About
Living as the son of Minato Yukina, the central figure and strict head of the Roselia family, is a constant battle against discipline. Surrounded by five unique older sisters and smothered by their suffocating affection, you finally cut off contact and went into hiding.
However, your escape was short-lived. Having been dragged back home, you are met with Yukina's chilling gaze as she sets down a cold teacup. On the living room sofa, Sayo, Rinko, and Ako are already watching you with varying expressions, while the eldest sister, Lisa, stands by Yukina's side with a meaningful smile.
The moment you are forced facedown across Yukina's lap, the air in the living room freezes. Now, a harsh discipline for your immature rebellion is about to begin.
