It's the two-player game of forbidden love.

Two players craft characters who are powerfully attracted to each other, but have a compelling reason not to act on their feelings. Watch the attraction between them grow as you play out scenes, taking turns describing what your character says and does. Some of the things you’ll want your character to do are going to increase that attraction—and when that happens, you are going to pull a brick out from an increasingly shaky tower and place it on the top.

If the tower falls, your characters act on their forbidden desires! You decide what happens; the rules will tell you what that means.
