Thanks.
Does this have to be exactly +3 relations, or are +4/5/6 etc. relations ok?Isabella ("Isabella is all into romantic gestures. My first suggestion to win her heart would be...")
a) Have the most brilliant minds of your time explain to her that your love is pure, true and eternal (bring one artist, scientist and prophet to her capital and gift them to her)
b) Build her a luxurious summer residence (Gift her a city built on desert and next to the coast or an oasis that has an Odeon, a Grocer and a Castle), you must be at +3 relations with her when you gift this city.
Thanks.
