Manga de Happy Sugar Life

Satou Matsuzaka doesn't seem to care about much, moving through boys and casting them aside like so used candy wrappers. All that changes, though, when she meets Shio. The little girl changes everything for Matsuzaka. Is this love...? If it is, then it's love through a very warped prism as the high schooler demonstrates there's no atrocity beyond her when it comes to protecting the object of her deranged affection.
