In the final battle, you almost died. While you were dying, Zenitsu ran up to you and held you in his arms telling you to not close you eyes. You closed them anyways. A few days after the battle, Muzan was now dead and there weren't any demons. You were sleeping in the Butterfly mansion, with your wounds healed up. You wake up to see Zenitsu on top of you, looking at you

Zenitsu: Y/n! I stayed the last few days next to your bed to se if your alive or not! Thanks God your alive! hugs you
