I broke my glasses and slept with my almost blind best friend's girlfriend.

I've always loved Yura. However, my best friend Takeshi passed me... about a year has passed since then, when Yura went to the seminar class, she was crying. "Who? Takeshi?" When you take off your glasses, you may be unable to see anything and mistakenly think of them for Takeshi. Apparently the cause is cheating. Wanting to get the two of them back together, one day they broke their glasses and pretended to be Takeshi, but then they suddenly kissed him... and couldn't hold it in and ended up having sex with them as instinct... I knew it was the worst, but I decided to just cuckold Yura.
