Author had ZERO idea where they were taking the plot and was just pantsing it the entire time. That's why the fated mate plotline was handwaved away at the end, and why the Yuu being handsy during Ao's heats ("I know your body best") also just disappeared. The end result is that everyone is a boundary-violating creeper.
I was waiting for the helpful side part glasses coworker to turn out to be the one digging through MC's desk, using the clingy lonely girl as cover for his stalking of the MC. My paranoia invented a plot twist that wasn't there, lol.
