Making an underage student a wife is not a good choice even if he didn't have a son. Bringing the underage student he was fucking around his son at all is a horrible parenting decision. The whole "wife" thing does not make the dad any less disgusting.
Taking responsibility would be to quit teaching and go into therapy so he can date women his own age, or at least fully grown adults.

i thought 16yo is a legal married age for women in japan, is it not ? and teacher student relationship is a clasic shojo manga plot... welll theres bit of H there but... and the son is a elementary student wich i believe not yet learn about save sex or so education wich i think the girl had... no matter what the girl still show thing like that to an elementary student...

Way to go for missing the point. The legality isn't the issue. The trope popularity isn't the issue. The problem is putting someone who is barely more than a baby herself in charge of your emotionally fragile kid. It's about being so self-absorbed and needy, he prioritizes his delusions and desires over the safety and stability of his son. Sure, the girl's a hot mess with a pitch-covered soul, but she's not the parent.

Well said! For me there's no way to justify the father. He's a failure as an adult, as a teacher and as a parent. He's a hypocrite stating he cares about Shirotani's well-being, while it's just an excuse to f*ck a young chick.
The girl's actions wouldn't affect this poor kid so much, if he could trust his father and rely on him.

True. In that sense, she's just a plot device. It's fun to dissect those. I was just getting tired of all the "Murder the Bitch!" comments, which just felt a little too much like people gathering for an oldfashioned witch-burning. I started to hope nobody who read the manga or the comments section went to school later that day and slapped somebody's face because they. were. just. so. PISSED. OFF. at. the BITCH! RAWARRRR!!!!table-flippy emoji here. (Of course, if they went to school and kicked Mr. Grabby Hands Course Advisor Pervert in the nuts, I'd have no problem with that. :-p)

Right. You can't control who you fall for. When you're as young as 16, you don't even have enough physiological impulse control brain development to always govern and ameliorate your behaviour in the face of those overwhelming emotions. That area of the brain doesn't fully function until your early 20s. There's the dividing line between holding someone completely accountable for inappropriate behaviour (like a professor who messes around with his students, assuming he is her sensei) and cutting them some (restricted) slack—not enough to let them near your kids again. I don't think this is a cultural thing, so much as common sense and awareness.

I'm well aware of that ;) An evil/crazy/jealous female character just has to create a plot twist in a yaoi manga, there's no other way. That's why I'm a bit disappointed by this one. I expected much more.
I'm still not convinced this whole "sexual therapy" is the best way to deal with sb's phobia, but whatever.

Babysitting is not the same as parenting--and if my child reacted to a babysitter like that I'd ask why and get a new sitter to see if that worked better. Most 16 year olds are not ready to be full time parents or married--and a trusted teach should not be having sex with a student. If it were a manga about a student-teach couple, I wold chalk it up to the fantasy of young people. But this is not about the forbidden love of children who act like adults. This is a man abusing his position to have sex with a student and then ignoring the effect it has on his child. Shiro-chan always reacted badly to her, but the dad just told him that he "knew" shiro really wanted to "be good".

I think Shiro reacted negatively to her, but his dad bulldozed over it with a smile and a "I know you really want to be a good boy", but that could be in the eye of the reader. The bottom line is this girl was (1) not mature enough emotionally to handle a relationship with an adult and (2) a student, someone whose parents trusted a teacher to guide and nurture. She was old enough to know better than to treat a kid like that, but the dad was way worse, both as a parent and a trusted teacher. He should have been thinking with his big head and not the little one.
I can't stop being mad to that bitch!!
BURN HER TO HELL
