I Time-Traveled and Confessed to My Teacher Crush

高2にタイムリープした俺が、当時好きだった先生に告った結果

Seiji Sanada, a corporate salaryman pushing thirty, wakes one morning to find himself back in the spring of his second year of high school. He has long regretted graduating without ever telling his world-history teacher, Haruka Hiiragi, how he felt about her. Handed a second chance, he confesses outright this time, and to his shock she takes it in stride. The two begin quietly dating, and Hiiragi turns out to be the kind of partner who spoils him without limit.
