@Justpoffo it's hardly even present to consider it "romance" tbh
There are a few cute moments with both main ships here and there (though it's mostly just Kashima inadvertently being cool lol) and there are some pretty cute scenes with the parents, but that's about all the romance that's there sadly
The series is kinda died down plot wise, case in point one chapter has Kazuma and Takuma get a botched haircut from their mom, but the next chapter right after their hair is fine.
