She suddenly has to play family with the guy she despises for a million yen?! Ichiru and Tsukasa were raised at the same orphanage, and were constantly at each other's throats like cats and dogs. They even got into a big fight on the day they parted ways. Ten years later, Ichiru is down on her luck after getting fired from her job, kicked out of her company dorm, and left penniless on the street. As she sits on a park bench licking her wounds, she's spotted by none other than Tsukasa, who's shot up in height and stature over the last ten years. Somehow he's now a bigshot CEO, and by the looks of it... a single father?! To make matters even more bizarre, he practically forces Ichiru to raise his child with the promise of a million yen if she can do it! How is she supposed to co-parent a child with him, of all people...? The three of them are an unlikely family, but can they learn to make it work?
