The first time you cook something in your kitchen each day, her LP increases slightly.

** Once you reach her LP 4 event and choose the option to slim down, she will hate these sweets. Give her flowers instead.

She will ask if you if you like thinner girls or not. If you choose you do, she will go on a diet, if not she will remain the same. She will become skinnier in the next week or so if she diets.

Talk to Eunice, don't ask her about the diet. Go shopping at Rosetta's store and enter the Lottery. You will need to do this a minimum of 3 times, then enter the store when Eunice is not there. Talk to Eunice, Turner and Rita immediately afterwards.

Afterwards, talk to Eunice for the next few days (it may take a week depending on the day of the week this started). Return to Rosetta's store and talk to who gave the ticket, then talk to Eunice again to complete the event.

*Sorry if it is hard to understand that one, it was difficult to give spoiler free directions for this string of events.*
