Cen Youmu had a crush on Yan Yuezhi when he was in junior high school, but he never said it out loud.
By some mistake, as an adult, he traveled back to the second grade of junior high school, only to find that the entire world line had undergone major changes. Everything was heading in an unknown direction, and the only thing that remained unchanged was his secret love.
Can Cen Youmu succeed in confessing his love this time?
Intention: The biggest regret in one's life is that he did not have the courage to say the words "I love you" back then.
