3-pun Instant no Chinmoku

Toujou Aki lives with his younger step-brother, Saku, who is a university student. Rather than returning home to sleep, Saku stays out with as many women as possible, living a highly promiscuous lifestyle. Aki, on the other hand, harbors a deep hatred for women, experiencing actual nausea when forced to be around them. Aki's one closely guarded secret is that he would do absolutely anything for his brother, no matter what it entails. However, everything can change in a single instant during three minutes of silence.
