Set in a post-Endless Waltz environment, all the G-pilots are now an integral part of the Preventers force. Heero and Duo are living together in apparent domestic bliss. But their relationship is suddenly shattered when out of the blue the Heero kicks Duo out of the house without any apparent reason. Can Quatre find out what really went wrong and make the ex-perfect soldier realize he's giving away his only chance at happiness? (or something...).
