.flow - Untitled (Doujinshi)

"Sabitsuki was once dead, but her parents managed to bring her back to life after countless experiments and mistakes. Now that she’s alive, her parents are worried about how she died in the first place, so they prepare everything in order for her to learn to enjoy life again. But being alive means to suffer sometimes, and therefore, happiness can’t last forever."
