Jilted and heartbroken, 20-year-old Kinoshita Kazuya turns to Diamond, a Rent-A-Girlfriend app that leads him to a fateful encounter with Mizuhara Chizuru, one of the talents on offer.
Not like these relationships 
last more than a day!
!كأنّ هذه العلاقات تدوم أكثر من يوم
Diese Beziehungen halten
doch eh nicht länger als ’nen Tag!
Et c’est que pour un jour !
Alla fin fine sono solo uscite che durano un giorno!
Esses namoros não duram nem um dia!
Всё равно будем встречаться 
лишь день!
