Ichaicha suru to Okane ga Waichau Futari no Hanashi

Money will spring!? A pure comedy about a man and woman's unrequited love! Aki, a boy with a blunt but gentle heart, and Haru, a warm girl. When two poor college students flirt, they get money for some reason...? A comedy about two people who flirt while pretending to be "for money," while keeping their love hidden from each other!
