I Swear I Won`t Bother You Again (Manga) Vol. 1

One noblewoman's attempt to rewrite the past--and avoid her descent into villainy. (And don't miss the original light novels, also from Seven Seas!)
Succumbing to long-simmering jealousy over her younger sister, noblewoman Violette snaps and does something terrible. As she languishes in prison, something unexpected happens: time is rewound, sending her back to the day she first met her sister! Armed with the memories of her disastrous first go-round, Violette is determined to take the script in a different direction this time.
