I'd say it's fair for anyone to feel uncomfortable, after all, neither of them wanted to have sex then and there, and it is both of their fault, Tsugumi's for absolutely refusing to take suppressants even for his own sake, and Megumi's for thoughtlessly approaching Tsugumi when he was in heat, losing control due to the pheromones. At this point, they've understood that it was really an unfortunate thing, and have moved on with a mentality of "what's done is done". But your feelings are absolutely fair as this type of scene can trigger many people...
In the first few chapters rape has been brought up numerous times, and that makes me uncomfortable... And the scene where they were locked up in a room (?), and they end up having sex while the uke says no made me uncomfortable too... Am I the only one feeling this way? And am I overreacting?
