One day, Tomoko sees popular idol Shion (Masahiro Higashide) on TV. She is surprised, because Shion looks exactly like her former classmate Jun (Masahiro Higashide). Suddenly, Tomoko makes phone call to her former classmate Harumi (Maki Sakai).
Harumi works at a bar and she barely manages to make ends meet. If she could do anything over, Harumi wishes to marry a rich man.
Kaoru (Reiko Takashima), who is a former classmate of Tomoko and Harumi, manages Shion. Kaoru is a single and lives with her mother.
Tomoko then gets a phone call from Jun and she is invited by him to meet at the coffee shop "Time." At the coffee shop, Tomoko also meets Kaoru and Harumi. They were all invited there by Shion. Shion then tells the women that he is Jun and he never ages. He offers to take the women back to when they were 17-years-old.
