We all love a box of chocolates on Valentine's Day, but a new campaign from the One Love Foundation contains some candies that have some bitter aftertastes.

That's for a reason: the special-edition box of chocolates, which was conceived, designed and developed by TBWA\Chiat\Day New York alongside a team master of chocolatiers, contains eight confections created to spark conversations about positive and negative relationship experiences.

The different creations represent four healthy and four unhealthy relationship behaviors: Respect, Honesty, Equality, Independence, Sabotage, Obsession, Isolation and Manipulation. For example, "Respect" is a strong, dark chocolate decorated with gold saffron, representing the gold standard in a relationship; while "Manipulation" is a chocolate filled with hard, sticky caramel that takes control of your jaw and is hard to swallow, and "Jealousy" contains a bitter core.  

The box comes with a piece-by-piece insert to explain more about each behavior and its effects. One Love is also running a contest to give away a limited number of the boxes to winners (maybe a gift for a toxic partner?)

It's a follow-up to a campaign last year that turned traditional Valentine’s Day gifts on their head to illustrate common unhealthy behaviors, selling them in a New York Soho pop-up store.
