It's interesting, MC and her husband seem like their personalities are similar but when you bring Bomborino into the mix it's clear that her husband is a bit more flexible and experienced with dealing with different types of people.
You can also see that MC and Bomborino sorta cancel each other out. They have different strengths that could compliment each other but Bomborino can't understand MC's technical explanations and his explanations aren't logical enough to convince MC.
