In this world, a romance app called "Love Alarm" has become widely popular, especially among high schoolers and young people. Love Alarm is an app that rings your smartphone whenever someone who has romantic feelings for you comes within a 10-meter radius. It doesn't display the person's name or face, so you don't know exactly who likes you. Since your own feelings are also transmitted to others, your alarm might ring just by being near the person you like. The number of notifications on one's Love Alarm often draws attention from those around them, serving as an index to measure romantic popularity and social standing. Rules of Love Alarm and Romance - Love Alarm rings when someone who likes you is within a 10-meter radius. - The name of the person who triggered the notification is not revealed. - If you like someone, your alarm will ring on their device when you are near them. - The number of notification counts is recorded and can be checked by others. - If romantic feelings fade, that person will no longer trigger the alarm. - You cannot know the person's identity or true feelings through the app notification alone. - The phenomenon of the alarm ringing (or not ringing) creates romantic opportunities and misunderstandings.
