In this world, soulmates from a parallel universe exist. Whether you were an Utopian, a Prestigious, or an Eccentric, everyone has a soulmate. On a person's sixteenth birthday, a mark is engraved into their wrist, signifying their relationship. Many have gotten hearts, some have stars, and others more personal like musical notes, flower petals, etc. The marking is what connects you to your soulmate. You, however, have an infinity symbol carved along with your s/o. Will you have enough time to experience all that you want to experience? Or will the impending doom of an illness get to you before time runs out?
