Hmm i think 1st ml and his ex girlfriend is not really in a relationship, i think 1st ml helping this girl and this girl friend to hide their relationship i mean they might be in a relationship (a Lesbian) and ml taking all the blame for them and that's why the trio are arguing because the girls doesn't want that and ohh the 2nd ml, i don't like him at all he is good looking and well build but not a relationship type of guy, for me he is just fuck buddy, a toy to play and ride on but not to be a lover. Period!
Ps: sorry for my bad language

I think mc is their son? The color of the hair and eyes are both taken to them and the power, genius and innocent of mc is also taken to them too.... And headmaster might not that old but because he lost his wife he withered like that just like the other stories when they lost someone special to them they're become older for some reason. That's my thoughts
He's so cute when he was young hahaha well he does till this day i mean older him is the same as way back him in the past hahaha
