don't know if someone's posted this already but it's not on the first page. I found the variable names for cheating purposes with the console
friendship points: v_stat_d_friend
love points: v_stat_d_love
the date night restaurant game points: v_day8_cupid_score <- you need 46 points to get the best outcome
you use them like this 'v_stat_d_friend = 50' or if you want to add 'v_stat_d_friend += 5' to add 5
afaik they're pretty save to mess around with, I've done it myself. higher points strictly just give you better/more possible actions without any drawbacks.
