Richie and Alice are a quiet, geeky couple who have been together for three years. At the start of a new college year, Alice finds herself getting attention from people who barely noticed her before.

Christine invites her into cheerleading and a more popular social circle, while Christine's brother Tony becomes her maths student. Richie is proud of Alice, but the change also brings feelings he finds harder to explain. Other people's interest can be exciting, flattering, or threatening. How he responds begins to affect the time they spend together and the conversations they avoid.

Choose a Richie-only perspective or include Alice's point of view. Her scenes show what she wants from these new friendships and how she reacts when other people try to decide for her.

Decisions build on Loyalty, Lust, and Vanity: support for their relationship, interest in outside attention, and wounded pride. The story explores how these motives can pull a couple in different directions as their familiar place in each other's lives starts to change.
