A realistic fiction comic series by black-kitten.

Half-identical lynx twins Sebastien and Serah choose to enter an incestuous relationship in their final year of high school. (The author has stated them to be 18 years old, but this is not always reflected in the art, which tends to give them an adolescent appearance.) The story explores the realistic consequences of this forbidden relationship, with the twins forced to consider their prospects for the future and the reactions of their peers. The story also contains themes of loss, grief, and substance abuse in the twins' family, which was shattered by the death of their mother several years earlier.
