Harvest Moon: Boy & Girl Requests

i need to know all the hearts events and rival events for cliff. ive looked at several websites and could not find anything on the subject.

i picked the request type randomly so don't mind it. anyway, i just wanna ask, whose going to be my wife easier/faster?? popuri or karen. i already have a blue heart with popuri and a purple heart with karen. they say that karen's the easiest. but really, who is easier?! i want to marry already so i can stay in the town FOREVER. i want a reply asafp!
