@sun what is polycule? isn't it a relationship with multiple people?

look is easy

if gender male you can marry one and have many concubines
if gender anything else you can marry one OR have single concubine
if male switches gender and has many concubines he loses them all and keeps marriage (if any)
circumventing the concubine limit thing outside of system means 10grans expropriation (has to be reported by another user to start investigation)
