what the hell?? mental age of a child us immediately creepy as hell, im dropping

Do you mean when he lost his memory... they didnt even do anything and he got em back soo...a mature adult now

nothing untoward happens during that time, it’s just used as a plot device to make the characters interact at first and for the ML to realize he sleeps very well around the MC (again another reason to force them to interact once his memories return)

don’t worry, it turns the usual flavor of toxic after that
