My new wife discovered my past

After coming to Tokyo with a changed face, Toru Watanabe, who had a traumatic experience with women, met Noriko Shimizu, a gentle, elegant and family-friendly woman.
In the 20th year after the rebirth, Toru Hei, Toru Watanabe, and Toru Watanabe had a girl they liked for the first time and experienced the feeling of love for the first time. After being in love with Noriko for four years and spending a wonderful college life, they entered the marriage hall.
Life should have been so happy and perfect. Watanabe seemed to have completely forgotten the four years of hell in Kyoto and was completely welcoming the new life that belonged to Tetsuya Watanabe.
Then, that woman, Saotome Hazuki, the culprit of everything, stood in front of Watanabe again.
"Long time no see~Tetsu-kun~"
"Finally, I found you~"
