Toxic.

Hope and Alec have one of those relationships they tell stories about horror stories. You see, while they may have the most intensely passionate sex life of anyone, they also have a volatility that makes a roller coaster look like a carousel. Their ups and downs are so intense that Hope spends a lot of time trying to make heads or tails of their relationship with the help of their two friends, but when the possibility for an open relationship enters the picture things will either tear the young couple apart or push them closer together.
