Uhm the way I see it the author doesn't do that. Some characters have that misunderstanding at first when they see them but for a purpose. In chapter 13 it was so that Aless develops feelings for her uk. And before that it was so that the ex girlfriend from Grey san gets jealous or something. It's not intended to ship Grey san with the eldest daughter in any way ╮( ̄▽ ̄)╭
I just came to read this because of the found family troupe but I hate it so much when it feels like the author is pushing romance between Grey-san and the eldest daughter he is LITERALLY their father who adopted them.
