I See Who Is Pretending to Be B

I thought I was just an ordinary person who traveled through time and was adopted by a gay couple, until I witnessed with my own eyes the fact that my brother was born to my little dad. They always thought I was an O and took good care of me until they discovered that I had no glands and no pheromones. The reason why I could smell other people's pheromones without having a penis was because I had a unique atavism. When I thought I would never graduate, the principal of Imperial First Academy found me and said that I could study there, but I would need to rely on my talent to find the guys who were pretending to be B in the school. At first I just thought it was a boring job. Later I discovered that this job was not as simple as I thought. For example, now, looking at the red-faced student in front of me, I don't know whether he is a durian-flavored O in estrus, or whether he is ashamed because I found him cooking shit in the dormitory. *** Note: 1.
