Question for those who have read the manga

It's like a father and daughter kind of relationship and it doesn't turn romantic.

@Ehppy There are very few manga chapters released so far and the relationship is kept at normal father-daughter level. I don't think that anything else is even possible, considering the father is a golem (machine) and the girls is a human (flesh). minor spoiler
They say "The first male a girl falls in love with, is their father." - in a non perverted way of course. So I'd say the relationship is perfectly normal.
