To Save Seven Villainesses, I Went Full Harem!

After crossing into the pages of a fantasy novel, I find myself in the role of a doomed antagonist with only three days left to live. Fortunately, a system offers me a chance at redemption: to prevent the world’s destruction by saving seven heroines from turning to darkness. The only way to achieve this is through genuine affection and connection, turning what was meant to be a tragic fate into a journey of heartfelt rescue.
