A long time ago in Western Europe, a magical world existed. The immortal witches there are invulnerable to fire and water, and only love can hurt them. Once they are loved, their lifespan will come to an end. The deeper they are loved, the shorter their lifespan will be. An ancient manual from an unknown source teaches witches to create someone to accompany them. What witches who are too bored to want to live have to do is get "love". The manual is called "Suicide Guide". ——"Let's name you 'Qiao'." "Ann!" "... My name is Andrea, not Ann."
Purpose: Good friends and companionship are both hard to find, so practice and cherish them.
