Gotoubun no Hanayome was originally published as a one-shot story in Weekly Shonen Magazine's 8th

issue of 2017. Thanks to the favorable response from the readers, it started serialization in the magazine

in its 36th/37th combined issue of the same year. 

Its English edition The Quintessential Quintuplets has been released by Kodansha USA under the Kodansha

Comics imprint since June 2018. The publisher introduces its story as below:

One day, a poor high school second-year named Futaro Uesugi comes across a private tutoring gig with good

pay. But his pupils are his classmates!! And they’re quintuplets!! A-and they’re all gorgeous girls, but they’re

also troublemakers who hate to study and are on the verge of flunking out! And his first task is simply gaining

the sisters’ trust?! Every day is a party! The curtain is rising on the Nakano quintuplets’ quirky romantic comedy

with five times the cute!!
