Must be funny to have a sense of smell that is good enough to smell out even small details and things like if someone had sex with someone else. Would be hard to keep things private then though, but I guess that we would've developed things to mask smells if that were to happen.
I love how the bunny girl (Haru was it? I keep forgetting the character’s names) reacted to being smelled xD like yeah... she gains a lot of attention from predators (also her face in the last page is great)
