Did they both just die..? I presume those were the twins in the afterlife? Or maybe it's just random imagery for some analogy?
Please, the final chapter, please redeem it.
@Refure The orphan sister already had the key since she was in the orphanage. She just kept it with her at all times. I'm not sure if the brother recognized her or not, but in any case she ended up at the place where the mute sister just arrived at.
Someone please correct me if I'm wrong or...
