Prologue

In Prank Goes Wrong, a stepbrother and stepsister share a house near their university, and his sexual jokes have turned the home into a fight. He steals her underwear and records her angry reactions. Each new trick gives him a fresh way to provoke her. Girl sees him as a pervert, but punishment never stops him. His next target is her favorite swimsuit, and the payoff comes in Episode 1. Friends join the fun later, and all episodes can show you where this war ends.

Manga tells a story of stepbrother Jerry and stepsister Laura, who live together. Both attend a nearby university, and a shared house costs less. The arrangement gives the brother endless chances to torment his stepsister. He steals her underwear from the washer, records her in private moments, and treats each angry response as proof that his prank worked.

Laura fights back with punches, punishments, and threats, yet none of them makes him stop. Jerry acts like an infantile trickster who wants every angry reaction for his phone. His cruel jokes hide a new attraction to a stepsister, which makes his next prank far more dangerous than his earlier jokes.

Laura sees Jerry as a stupid pervert and the source of every problem inside their home. She has no reason to expect desire from him or in herself.

The payoff waits in A Sweet Gift, where his peace present pushes the war into new territory. Sharon joins the story after that, and her interest in Jerry forces Laura to confront feelings she wants to deny. Read all chapters to see the choice the main characters will make after the truth comes out.
