Dude, we can clearly see that the MC considered them as his own child , he litteraly say that MANY time. Everytime he meeting he's kid he insists on the word FAMILY. Idk for you but when someone tell you , your he's family , it's mean something deeper than just on paper. Which make you the delulu one btw. Plus , i don't think you actually know what the word incest mean , (which is also concerning.... ) Basically it's mean someone who is voluntary to protect you and basically TREAT YOU LIKE HE'S OWN CHILD , so yeah normal people don't dream about wanting to get marry to their parent and even ADOPTIVE PARENT. Do you want to marry your own mother ? If you think no than we're on the same page
I think it's funny because you the typical profile of someone who read that kind of story that normalise that kind of shit , and sudenly think it's a normal behavior bc " everyone do that ". Bro i have to hold your hand when i'm gonna tell you this , but that shit is not normal , that's why incest is forbidden in most countries. I mean... you can have fetish if you want , who am to judge you . But just don't try to think it's a normal behavior , or don't try to marry your adoptive daughter in Real life. Cuz you know, that way of thinking that you have is more dangerous than you think. Be better.

Y'all killing your own mood over some love interesting and I'm laughing at y'all comments while eating ice cream. honestly its not that deep to me I'm more interested in the magic he gathers
