Ooh. Thank you.
Person A's grandfather had been in love with a woman when they were young but for some reason they couldn't get married. So they thought wouldn't it be great if our grandchildren got married. Person A is appalled that the grandchild of the woman (person B) is also a guy but no one listens to him so A and B get married. A falls in love with B and B loves A. Then the grandmother died and A's mother starts trying to get rid of B. Does anyone know this? For some reason I didn't save it.
