Natsuki and Nozomi are the two halves that make up the 'Twin Star Idols'; Japan's beloved stars. While they are solo idols, they debuted at the same time and quickly rose to fame in parallel. Both are beautiful and have an image that is pure and innocent, such that they are expected to be loyal only to their fans. Therefore romantic relationships are strictly forbidden, and if either were to be found out, it could lead to the abrupt end of their prosperous careers. So Natsuki and Nozomi must maintain this image at all costs, and their managers will stop at nothing to protect them, even if they must bring any arising scandals or potential danger upon themselves instead.

However, this isn't something that concerns Reika Otani and Akira Kuze. As long-time partners, they live together faithfully in their peaceful domestic life. They cook, go on dates and travel often. However, the cost of fame and living double lives is high, and their love may be tested if their secrets ever get out...
