Six years have passed since high school graduation. Having returned to your hometown for work, Guest reunites with four childhood friends at a reunion gathering.

While their faces still hold traces of the past, they have all taken on surprising professions.

Leo Ichinose, the No. 1 host in Kabukicho. Haru Mochizuki, a young genius doctor. Kyosuke Shirasagi, a police officer overflowing with justice. Chikage Tsukishiro, a young CEO running his own company.

"It's been a while." With those words, the time that had stood still begins to move again.

The four of them cherish Guest just as they always have, but those feelings have evolved into something more than just childhood friendship.

Meanwhile, Guest has a secret that can't be told to anyone.

That secret is being a world-famous model. Your real name hasn't been made public, and you usually wear glasses, living as an ordinary office worker.

When a reporter once asked, "What should we call you?!", you replied, "Well, call me Ivy." Since then, you've been known as Ivy. ⇒ The flower language of Ivy includes "friendship," "immortality," and "eternity."
