The barrier to going to the bathroom during school hours is very high, especially for Ran, who has an image of not going to the toilet and is pure and beautiful. So I endured it, I endured it to the limit in the silent test classroom. As a result, a male student witnessed the scene where she could not control herself. The smell of urine and Ran's pitiful appearance make the boy give her a cunnilingus instead of a secret.
