Why are there comments defending grooming? You know it's bad when you gotta give the word a definition to excuse it. The nurse is grooming Mizuki, even if she doesn't know it(which I highly doubt), and even if it's fiction there should be an acknowledgement of this in the manga or from the author. You people should stop normalizing pedophile in media or else it'll normalize by kids in real life who read these stories and think it's okay to replicate it.
