Curious About Today's Omen? Fortune App 〈Night Omen〉

Curious About Today's Omen? Fortune App 〈Night Omen〉

Around sunset, the phone screen briefly lights up.
"Today's omen has arrived."

Recently, interest in Saju (Four Pillars of Destiny) and tarot content is rising among the younger generation in human society. Moving beyond simple consumption of fortune-telling, this trend is expanding into a culture of capturing and sharing results and comparing compatibilities with one another. Interlocking with this atmosphere, a dedicated fortune-telling app 〈Night Omen〉, which is updated every night, has also emerged in the vampire world. Within half a year of its release, the number of users has rapidly increased, establishing itself as a natural daily routine among the species of the night.

Checking one's fortune no longer remains a solo act. Users share phrases like "Top-tier emotional wave today" or "Strong lunar phase influence" on social media to check on each other's nights. It replaces the role once played by zodiac astrology or red crystal balls.

Night Omen analyzes the energy flow of the night based on the user's lineage, years of life, and the lunar phase of the day. It reveals overall rankings every night, and a one-line piece of advice such as "A night when senses sharpen, take the lead in conversations" is attached for top-tier users. Subsequently, a detailed report is provided in a card format covering emotional waves, interpersonal relationship fortune, concentration fortune, and the bloodfeeding impulse index. At the end, 'Today's lucky color' and 'Stimuli to avoid' are organized. It looks similar to fortune-telling apps in human society, but differs in that it cross-analyzes the lunar phase and biological rhythms to predict thirst-sensitive intervals.

Of course, skeptical views also exist. Some point out that "It is ironic for a being living an eternal life to be shaken by a daily fortune." However, the number of people checking notifications around sunset is steadily increasing. Especially among young vampires who have not been active for long, the process of sharing and interpreting the results itself functions as a form of play and a method of communication.

To beings living eternity, a single day might seem trivial. However, within endless time, 'today' actually feels more ambiguous. H, a 300-year-old office worker vampire, says, "Since we live for a long time, it feels like the macro direction is already set. Instead, it's easy for the daily rhythm to get disrupted. Night Omen allows me to check the start of my day as if looking at a weather forecast." To avoid losing our way within endless time, today once again, we listen to the short text that arrives around sunset.
