Yukari is dull. He doesn’t even stand out enough to be bullied—he’s just a generally lower-middle-class kid. One day, on the eve of his sixteenth birthday, he confesses to his childhood crush Misaki Takasaki. There’s just one problem: He was 15, few minutes away from receiving his government-assigned marriage partner. He normally wouldn’t have the courage to defy the law, but his assigned wife Ririna still believes in love, and won’t stop goading him into confessing his feelings!
