The official Twitter dedicated to the manga revealed that it will have two different endings: a "marriage route with Misaki" and a "marriage route with Ririna."
The author is taking a break to write the manuscript that he himself claims will be the " ideal ending " for the series. He also stated on Twitter that he decided to create two separate endings for the manga five years ago.
Synopsis
Yukari is a boy who doesn't even stand out enough to be bullied – he's just a lower-middle-class kid, and he's in love with Misaki, the most popular girl in school. There's just one problem: he's 15 years old, one year away from receiving his government-assigned marriage partner. He wouldn't normally have the courage to defy the law, but his classmate Ririna still believes in love and keeps urging him to confess his feelings!
The work inspired an anime that premiered in Japan in July 2017. Seiki Takuno worked with LIDEN FILMS as the anime's director.
Furthermore, it's worth remembering that the 11th volume of the manga, released in December, had already hinted that the work was nearing its conclusion.
Musawo , the author of the work, therefore launched the Koi to Uso manga on the MangaBox in August 2014; within a month, the work was ranked as the most popular on the app, with a total of 3.5 million readers .
