Kou-2 ni Time Leap Shita Ore ga, Touji Suki datta Sensei ni Kokutta Kekka  

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

In my 30s, I was working in a corporation when suddenly, upon waking up, I realized that time had jumped forward to the beginning of my second year of high school. At this point, there was a teacher whom I regretted not confessing to earlier, so I did so impulsively. Now, we're dating, but she has a tendency to make men feel worthless, which means I am spoiled by her quite often. Despite secretly dating my overworked school teacher (my lover), our relationship is filled with flirting and sweet moments.
