@Odina21 what im saying is that this level of intrusion is inappropriate and although it might not constitute a breach of educational ethics its a pretty shitty move. Like so much of what Momoko has done already, letting her grades slip, sleeping in class, taking on a second job, is a red flag. Any educator who gave half of a fuck about their students well-being would've asked whether or not anything was happening at home. and in chapter five she straight up told him she was taking care of a child, not her child, and not alone, but she made it clear that she'd taken on extra responsibilities at home. But guy just jumps to conclusions about her character all while making flagrant assumptions about her home situation. Poverty isn't uncommon! students working to support their families is not uncommon! food insecurity is not exclusive to adults! Of course students would prioritize the health and wellbeing of themselves and any dependents over their grades! Even if he didn't know that it was due to her household, information which she has been shown to give freely if asked, her behavior could've been indicative of an unhealthy or abusive relationship or some new external source of trauma.
basically if Wakaba had started displaying this sort of behavior, and the teacher had acted similarly- reprimanding her, attacking her character, blocking her attempts at self-sufficiency while not providing any alternatives- he would've driven her back into the arms of her abuser. If a student who was being abused had started doing similarly then what he was doing might've made them drop out. Whereas a perceptive homeroom teacher might've noticed Wakaba had no friends, they might've noticed she was abnormally withdrawn, and they might've tried to reach out to her as a result. Like abuse doesn't happen in a vacuum! The scenario presented in this manga is very much not a vacuum. The apathy of surrounding authority figures gives predators like Asakura-sensei free reign over people in vulnerable situations.
also given that he knows that she's helping take care of a new child- he's seen the gossip flyer and shes told him that theres a new baby in her house- he might've went through the effort as an educator to connect like a single dot and assume that she's working + not getting sleep because shes helping support him- then apologized to her for his prior misunderstanding. But i guess something like assuming a student is a human being deserving of respect with a life outside of school and not just a machine that's broken if it doesnt study wouldn't mesh with his teaching style.
edit: also like the bar must be below the ground to assume that someone is a good teacher bc they aren't a literal sex predator. academics aside we haven't once seen this guy show compassion to a student. we haven't once seen him not link a students grades to their worth and morality. if you went to this school and you had a personal emergency who would you rather go to? If-You-Don't-Get-Good-Grades-You're-Scum Sensei or the guy who's straight up said you can go to him for advice? This is what i mean when I say abuse doesn't occur in a vacuum. Predators love this sort of dynamic because it means even more vulnerable people will go to them, get attached to them, and stay with them because they feel that they won't find any support otherwise
