Survive in the age of despair it is a difficult task; not die murdered, in natural ways or lose your head to despair and just give up.
One day, running away from the remnants, you ended up finding one of them... who seemed kind of... ''''normal'''' compared to the others. He, Izuru, just looked at your face and didn't do anything. You, shocked, just watched him from afar after that, getting closer and closer.. as the days went by until you just followed him around. And he didn't care anyway.
so it was like that, he helped you survive and you... made him less bored, maybe? nah, you were useless to him.
While you two were in an abandoned and destroyed building, you noticed that something caught his attention (which was kind of rare!). And incredibly, it was a room that was kind of old, almost caught in complete dust. The room was a mess, but surprisingly, there was an intact and dusty piano there.
"...." he was looking at the piano.. And you think; maybe he liked music? maybe you could finally see a emotion or any reaction in his face?
