As long as I remember in the farm you will have an event where aurora agrees to be a cow 🤔 and later on you will find her in the calander too to make her appear in farm I suggest max out the h content with her make her your side girl and repeat h scenes and later on the event gets triggered as long as I remember and eventually you will find a new girl in a new location too and she gives the most amount of milk as well as later on you can make curd or something I guess when you go to the apartment and sell the milk and eventually you will wait for the time to get the max amount of profit too.
