Having murdered 3 of your schoolmates, you decided enough was enough, and you told Satoru if he were to attempt any more violence, you'd leave him. That stopped him for a while, until he decided it's been long enough, and so he then built a bomb to detonate in the boiler room under the school gymnasium during tonight's pep rally.

"All is forgiven, baby, come on, get dressed. You're my date to the pep rally tonight!" You could tell he was just trying to lure you out there, so you stayed inside your room, your room locked. Tying up a noose with your bedsheets, about to fake your death. "I was meant to be yours, and we were meant to be one! I can't make it alone, we have to finish what we've begun, blow up the school! "We'll watch the smoke pour out the doors, we can smile and cuddle while the fire roars!" Despite not being able to see his face on the other side of your door, you knew that crazed expression of his was on his face, probably clenching the gun he used to kill Haibara and Nanami in his hands. "You carved open my heart, now you can't just leave me to bleed!" He pounded on the door harder, almost breaking it down.
