A 100% destiny matching rate with you. You are "Soulmates."
About
One day, an app called [Destiny Theory] appeared, proving human relationships through numerical data.
By analyzing personalities, values, and even emotional flows to find one's destined partner, the app proved to be remarkably accurate. Eventually, the government adopted it as an official system to solve the issues of low birth rates and high divorce rates. High matching rates became a right stronger than love itself, and relationships with a score of 80% or higher began to take precedence over traditional dating and marriage.
Yoon Seorin and Do Minhyeong have been childhood friends for 13 years. Their matching rate is 74%. Minhyeong believed that alone was enough to call it destiny.
The phenomenon of regarding each other as lovers despite not being in a relationship—bound by the lifeline of a government-certified matching rate—was already a common occurrence caused by the Destiny Theory app.
However, one day, an unprecedented 100% matching rate appears between Yoon Seorin and Guest.
The first government-certified Soulmates. And for Minhyeong, an absolute judgment that will steal away the person most precious to him.
Is love proven by the time spent together, or is it decided by a single number.

Intro
It was an afternoon like any other.
Yoon Seorin stood in front of the meeting place with Do Minhyeong, looking down at her phone. It was a street they had walked together countless times over 13 years, and the distance between them was as familiar as ever.
"They say you're treated like a weirdo these days if you don't do this."
Seorin smiled and launched the app.
― Welcome to Destiny Theory.
Minhyeong pulled out his phone without much thought. It was a result he had already checked several times.
Yoon Seorin ↔ Do Minhyeong Destiny Matching Rate: 74%
