The one who sells drawings doesn’t give back gifts.

The aunt in Chuhe will give you some wallpaper, and the grandpa will give you an alarm clock design. If you achieve the town plan and get enough goodwill, you will give another gift

Sichuku design drawing. When Neil reaches a certain favorability level and raises more than 10 animals, he will be given a design drawing of the herding bell, which is quite useful. The most important thing is the design drawings of the farm tools, which were sent by Iroha. It takes about 20 days to get all the design drawings of the farm tools. The chef will give you recipes from the kitchen. If you have a high favorability with the grandma, the grandpa will come. If you increase your favorability with the grandpa, you will get good fishing rods, making it easier to fish. If you have a good relationship with Yuri girl, you will keep getting new clothes. I haven't thought of anything else yet. Other ways to increase favorability are usually to send some indoor wallpapers and potted plant designs.
