Rebirth: Re-Chasing My Childhood Sweethearts

Every year, I receive birthday gifts from my childhood sweetheart. She actually still remembers my birthday. However, it took me a long time to understand her intentions. It turns out that she had died four years ago. I couldn't believe that I was walking on the street in a daze, and then I was hit by good luck and was reborn back to my junior high school days... This work borrows from Ye Yui's I Really Don't Want to Fall in Love, but they insist on it, so there may be some similarities in the plot, but the author is a novice, please be considerate.
