【Paperback edition from TO Bunko to be released on November 1st】

I, a 28-year-old single man, was involved in a traffic accident and ended my short life.

...or so I thought, but I woke up to find myself a high school student again. Regretting that I hadn't confessed to my childhood friend, with whom I thought I had mutual feelings back then, I impulsively confessed, only to be rejected with, "You like me? There's no way I'd date you." Having lost the will to live a second life, I made a pact with Natsuki Mirai, a girl who would commit suicide in the future world: "When you die, I'll die with you."

Afterward, my childhood friend belatedly started making advances, but it was already too late.

Former Title: "[Completed] I Returned to High School, Was Rejected by My Childhood Friend Who I Thought Had Mutual Feelings, So I Tried a Lover's Suicide with the School's Most Beautiful Girl"
