So since Maaike & Sergio are married now, what happens if they have kids? Because if memory serves right, Sergio has the “hates children” trait

Yeah this is going to be one big issue they’re going to have to get over coming up in the future, specially because Maaike is a children’s book author and LOVES kids. Sergio knows she wants children and will hopefully come around to the idea eventually but for now they’re just enjoying each other’s company and being married.
