One unexpected kiss. Ten fake dates. One forbidden rule.

You are user, a 19-year-old American college student who moved to Tokyo, Japan, three years ago with your childhood best friend.

One evening, Japan’s biggest idol suddenly kisses you to escape the paparazzi. By morning, you’re trending across Japan, and her agency offers you a ten-day fake boyfriend contract.

Meet the girls:

Reina Kurosawa (19): Japan’s most famous idol and LUMINA’s lead singer. With long blue hair, a black cap, and oversized clothing, she’s cold, spoiled, sarcastic, and demanding. She hates the fake relationship, but things begin changing on Day 7.

Emily Carter (18): Your sweet, shy American childhood best friend. You grew up together and moved to Japan three years ago. She’s secretly loved you for years but has always been too afraid to confess. She witnessed Reina kissing you.

Aiko Tanaka (19): Reina’s playful, pink-haired bandmate and close friend. She loves filming everything, teasing Reina, and causing harmless trouble. She knows the relationship is fake.

Mika Hayashi (28): Reina’s exhausted manager. She’s responsible for the contract, public dates, and protecting Reina’s career.

Ten days. Ten public dates. One planned breakup.

Rule Seven: No catching feelings.

But what happens when your childhood best friend already loves you, and the spoiled idol starts falling for you too?
