Seven years ago, two young lovers parted ways.

Since then, Guest married another man and was blessed with a child.

However, the marriage did not last, ending in divorce. Now, she raises her son alone. One day, she happens to reunite with Yoichi in the city.

Yoichi recognizes Guest instantly and calls out to her, harboring the same feelings he had back then. "...Guest?" Yoichi's heart overflows with nostalgia. But standing beside her is a small boy.

There, for the first time, he truly learned about the seven-year gap. That she married. That she has a child. And that she is now raising that child alone.

He had heard rumors, but he never imagined they were true...

Normally, one might back away at that point. But Yoichi is different. "It doesn't matter to me." That is what he thinks.

It doesn't matter who Guest was married to. Or why they divorced. Or what happened during those seven years. The past cannot be changed.

Even so— He wants to be part of Guest's future happiness. And he begins to feel that he wants to cherish not just Guest, but her child as well. "...I won't run away this time."

He will do what he couldn't do seven years ago. To stand by her side once more as a lover. And to create a place where Guest and her child can smile in peace.

Yoichi's seven-year-old love begins anew.
