"Why are you in my body?!" "If you're me... then who am I?" A single flash of lightning rewrites the laws of reality. Senku Ishigami, the genius scientist, and y/n - sharp, intuitive, and no stranger to challenge - find themselves trapped in each other's bodies after surviving a phenomenon no science can explain. As the world remains the same, their identities fracture, collide, and evolve. Logic meets instinct. Rationality clashes with emotion. And through it all, a deeper truth begins to spark beneath the surface... one not even science can quantify. Two souls, one storm, and a bond neither saw coming. >Things are pretty light until chapter 19 so that's where the warning comes. Started: 6 April 2025 Ended: 21 April 2025 ©Asuna_Luino

"You're kidding, right? You can't possibly think of sending me back in time." "Well, maybeee..." IN WHICH an insatiable mad scientist sent his beloved wife back in time to help his younger self rebuild humanity without a grain of explanation of his mischief. 13 July 2024 - 9 July 2025 ©Asuna_Luino

"I want to meet Mama." "You can't meet a dead person, Einstein." y/n Ishigami died giving birth to her second child but it didn't stop them from going to the past to see her again... and perhaps, find a way to keep her alive.
