You should get the option for Livrea if you flirt with her when she is in Hawkthorne and then when she is in Khor'minos she has a second date option.
I alwaus do the
Hawkethorne scene and the
Khor'minos dates to have acess to Livrea as a lover, as after
Hawkethorne the first and second date events always happens at livrea's ussual spot near the
Passion Pasture but this triggered at the
Milking Barn.
But i think this is an different scene wich i only got it to trigger once.
And it triggered when visiting the
Milking Barn, where she states 'she is waiting outside for her sister and niece but they probably are getting all 'milked' in there by the bulls and have forgoten about her as this isn't the first time they let her hanging outside in the cold when they go together to the milking barn'.
Than you get an option to ask her for a dinner or just move along.
