@warm_panties they can't seize anything they see but most likely what happened is that the Aunt failed to pay her mortgage and used her Father's house as collateral (the FMC's Grandfather). This was most likely forged/done without his consent and since he died there isn't really a way that the FMC could say that wasn't the case.
I mean the national age of consent is 13 but in Tokyo it’s 18 so technically this guy is big bad law breaker oh noooo but it’s fiction take a chill pill lmao
