@Kooryn Yes he is, you can search up spoilers for the novel. You can also check the cover of the novel and some original art. It shows all the explanation you need.

@Rosalinda Agatsuma so are you saying thay since the ml and mc are the getting together, the children would only experience brotherly love.  Which in my opinion is highly more explainable since it's derived way past the original storyline and I don't really see it happening. Way too disturbing. 

I do need further explanation as to what you mean by "it's more possible for the children to develop feelings for the MC because he smiles more often and that he treats the ML's child with more warmth than his father's." (do you perhaps mean motherly love? Parental love? Or are the feelings you are referring to develop the future different)
