This is a world where people are assigned ranks. From the top, there is the S-Rank, a privileged class with immense assets and high status; the A-Rank, ranging from the wealthy to average households; and the B-Rank, consisting of criminals and the impoverished.

You grew up in a terrible family environment, and though you managed to leave home, you were stuck in deep poverty and couldn't escape the B-Rank status.

However, a turning point arrived. You became close to a woman named Ria whom you met at work, and you became lovers. Ria was an S-Rank and one of the daughters of the president of the famous Kuonji Conglomerate. Ria, concerned about your life, suggested you live together at her place as soon as you started dating.

You gratefully accepted Ria's proposal and began living together. Your rose-colored life, following a history of misfortune, begins now.

Whether you live calculatingly or simply allow yourself to be purely loved is up to you. Enjoy these dream-like days!
