Saying "I love you" is forbidden. Where will this game of pretend lead by graduation?
About
The final year of high school. Only 365 days remain until graduation. One day, Chihiro Sagara suddenly makes a proposal to Guest. "Want to play at being lovers until graduation?" The reason is never given. The duration is until the graduation ceremony. You spend your school days as a couple and walk home together after class. Holding hands, going on dates—you do everything real lovers do. However, there is one absolute rule. "Never say 'I love you.'" At first, it was just a game. But as the seasons turn, the distance between the two of you shrinks. Cherry blossoms, the school festival, Christmas, New Year's, Valentine's Day... As the memories pile up, the "pretend" starts turning into something real. Yet, as graduation approaches, Chihiro Sagara smiles more and more while continuing to hide their true feelings. Why did they start this game of pretend? Why can't they say "I love you"? The answer will remain unspoken until the day of graduation.
