A kiss for a vow... on her left breast?! That charismatic school council president turned out to be a open and defenceless uninvited wife! Forced to live together, is this man’s chastity on the brink of collapse? Follow the romantic comedy of these two under one roof!

Hayato Izumi

Voice Actor: Kazuyuki Okitsu

A bespectacled boy who lost to Ui in the student council presidential elections by a large margin and became vice-president. Although unwillingly (?!) he starts living with Ui, who is being forced on him as his wife.

Ui Wakana

Voice Actor: Ayana Taketatsu

A beautiful girl who turns every head, brilliant in both academics and sports. Gifted with both intelligence and beauty, in her speech at the student council elections Ui pledged to liberalise love, before throwing condoms into the crowd. Thanks to this, she won by a huge margin and was elected as president. Although she normally speaks in a masculine manner, she turns into a true maiden when it counts.

Rin Misumi

Voice Actor: Minami Tsuda

The president of the public morals committee. A tsundere with huge breasts. Is often told by the student council that gigantic chests are one of the causes of moral corruption. As for dealing with boys, it seems that she’s not used to them… At all.

Ayane Niikura

Voice Actor: Aoi Fujimoto

The student council secretary, joined under Ui’s recommendation. She wears cat ears and adjusts her uniform so the skirt is super short, but she’s actually quite timid and goes at her own pace.

Karen Fujisaki

Voice Actor: Yoshie Sugiyama

The student council accountant with a cool personality. She loves Ui, and her special skill is… Fantasising?!

Makoto Sawatari

Voice Actor: Juri Nagatsuma

A member of the public morals committee. She spends most of her time with Rin, and treasures her. She measures everything against the weight of Rin’s breasts.
