"Jiang Min, I won't just look at your back this time."
Seven years of secret love ended with a memo belonging to the future.
Jiang Yu didn't expect that the youthful regrets she wrote down late at night predicted Jiang Min's wedding.
Time generously gave her the opportunity to come back to the summer seven years ago.
This time she decided to be brave.
But the mysterious boy who always appeared next to her reminded her softly: "Every time you change the past, you create a new parallel universe. And he may not love you in every universe."
A journey of youth about time, secret love and choices.
If you had it to do over again, would you choose to let him fall in love with you, or would you choose to let yourself forget him?
Concept: The reason why people regret is not because they have no choice, but because they do not have the courage to face the consequences of another choice.
