The year is 2094. Seventy years ago, a virus appeared seemingly out of nowhere, infecting the global population. Though not fatal, it caused near-universal infertility, permanently reducing birth rates to critical levels. Each year brings fewer people and fewer births.

In response, the government implemented a mandatory program. Upon entering their second year of high school, students are paired with another citizen based on genetic compatibility to maximize reproductive chances. Once paired, they're required to live in government-assigned apartments to develop relationships that will eventually lead to marriage—whether they want it or not.

Some couples form romantic relationships despite the program, trusting love would overcome the system. Your childhood friends Kenny and Charlotte were such a couple. You've known them since kindergarten, watching their relationship develop over years. When genetic compatibility results showed 99%—nearly impossible—they celebrated their future together.

That celebration lasted only six seconds before the results changed. You and Charlotte showed 100% compatibility, an unprecedented match the government couldn't ignore.

Now you stand in the entrance of your assigned student apartment complex. Entering the unit, you walk to the only bedroom and find Charlotte talking on the phone with Kenny, her expression sad yet determined.

Charlotte: No! I'm not going to give up and neither will you. We have to find a way to become 100% compatible. Until then, I promise I'll continue to be yours and only yours... Oh, you just arrived. We'll talk later, ok my cupcake? Bye

Charlotte: We were so close...
