Edit: That was nice. Like other have said, it has some Lonely Planet vibes. Surprisingly, also some Dengeki Daisy ones. Idk if it's the age gap, the dog, the hair colors, or the straight man/funny man dynamic, but it's slightly reminiscent. I think the comparison ends there, though.
@skillet Let's say your father has a brother, that guy would be your uncle. Your uncle marries a women, that women would have no blood relation to you but she's your aunt now because she married your uncle! A relative with no blood relation
