TBH, I don't think that the snake boys are deserved to be called 'cute' or 'adorable'.
I honestly dislike it when those little boys spoke those hurtful words to their mother, uke. Look, their mother, a man, was raped many times by their father, then had an unwanted pregnancy. But that pitiful man still somehow learned to accept and welcome them, no matter how bizarre that was. The first thing they do? Ignore and be rude to him, not once but multiple times. Ultimately, They called him their father's mistress. I know children are supposed to be innocent, and they have the right to be angry, but what these boys do is just simply too much.
Even the Seme is detestable. He said that he loves uke, but he just let those brats behave rudely to their pitiful mother, without feeling any discomfort. Ha, what a plastic love he has!
