This is a visual novel about 60 minutes in length, telling a story of memories.

"Once'" is a story which will recall the experience of many individuals. Regardless of if you're in your springtime of life having full of dreams for the future, or if you're a matured adult who has already stepped into the society and owns a family, you will all somehow spot traces of yourself in "Once'". Because that‘one time' not only exists in the game, but it also belongs to each one of us. It's a heartwarming story with moments of joy and regret.

This was once in my memory.
Yet only once.

So far away
Like a glance
Even, left out in the irreversible past…

Nevertheless, I wish, please
Always be able to recall
And engrave it on your mind --
Your
Only once, in this whole life.
