Echoes of Us

Nene avoided her death, something only one other person had ever done. Now, she's off to college in America, ready to start fresh. There, she meets the man of her dreams: tall, tan, handsome, and brunette. It's impossible not to fall for him. They fall in love, get married, and have a baby, basically the start to her life.
But luck doesn't like to stay long around Nene. Her husband passes away, and soon after, Nene loses her job. Struggling to provide for her child, she makes the difficult decision to move back to Japan to live with her mother.
By coincidence, she arrives just in time for Kamome Academy's reunion. Curiosity gets the best of her, and she decides to attend. To her surprise, the old bathrooms are closed down, does this mean Hanako's legacy has faded? Is he still an apparition haunting the school?
Before she can dwell on it, she bumps into someone unexpected, a very much alive version of Hanako. He claims he never died and is now working as a teacher in the elementary school.
Confusion sets in. Has she stepped into another picture? Did Hanako never exist as a ghost? Was he human all along?
