Dear My Sister

I remember me, Haruka, Hiromi-senpai, Kouhei, and my younger sister, Mari, all playing together... until a horrible incident drastically changed our lives: the death of my sister, Mari.

My father wanted to bring Mari back to life and so he created a new Mari.

A life no different than before. The same conversation as before.
But something inside me changed little by little.
