From the introduction:
Role-Playing Adventures in the World of Love
...
Role-playing game supplements focusing on love and romance are as rare as a unicorn and almost non-existent. Biggest publishers cautiously tiptoe around these subjects, afraid of touching adult themes associated with the topic. And unrightfully so, because love can be a fantastic addition to any gaming session, providing characters that feel alive, a genuine and warm storyline filled with sweet embraces, or maybe a dark intrigue weaved by a dangerous yet alluring enemy.
This book aims to fill this gap and is intended for Game Masters. Tome of Endless Romance introduces a full roster of 50 Non-Player Characters, along with their soft spots, moods, personalities, romantic backgrounds, and quests, each focusing on love.
