Gotta give the old man credit, he was in love with his high school teacher so much, that even after being her for a few short days, he still looked after her kids, and gave them a comfortable upbringing. He may not have been the best father but didn't give up on them, despite them continuing to do badly at school.
BTW: did we ever find out what happened to the Quintuplets actual father, and Fuutaru's mother? I don't want to assume they are dead.
