The title has been changed yet again. What a fool I am. Please forgive me.

The protagonist, Shuya Tokui, deeply regretted a foolish act he had committed towards his first love eight years prior. Though he was finally granted an opportunity to apologize after eight long years, just as he resolved to make amends, he was killed in a traffic accident... or so he thought. Upon waking, however, he found himself time-leaping back to his high school days. Regretting his past actions, Shuya began to devote himself to guiding his first love towards a better destiny.
