The Person I Was Matched With Turned Out to Be My Ex-Girlfriend

As marriage rates plummeted, the world passed a new law: every citizen would be assigned a partner upon reaching adulthood and forced to date.

After breaking up with his academically gifted ex-girlfriend, delinquent and failing student Lin Lu devoted himself to his studies, determined to turn things around and become number one. Meanwhile, his ex-girlfriend's grades took a nosedive, and she became a gal.

Though the two had become strangers, they were assigned to each other as adults and forced to date. They agreed to three rules, including not interfering in each other's lives, but the government sent out "Romance Inspectors" to make sure couples went on regular dates, lived together and shared a bedroom, got married within three years, and had a baby within five!

Even more absurdly, the partner-assignment System glitched and kept assigning Lin Lu more and more partners!

Green-tea girlfriend's best friend: My best friend won't get mad if she finds out, right?

Bratty little sister-in-law: Dummy♡brother-in-law, didn't my sister teach you this? You're such a loser~

Cool little sister: If I end up pregnant, we can just get rid of it!

Yandere idol and childhood friend: Hey, you smell like another woman, don't you?

Watching Lin Lu spend every day leaving early and coming home late, forced to go on dates with different girls, his tsundere ex-girlfriend finally couldn't take it anymore!
