Hearts

At a minimum, talk to every resident each day so that you can raise their affection and progress events at a steady rate. Gifting is recommended if you know what the villager likes. Here's what we've found them to like/love so far:

The order goes like this:
5 hearts | 3 hearts

• Doraemon: Dorayaki | Tempura
• Sue: Baked Potatos | Cheesecake, Hydrangea (summer foraging)
• Big G: Curry | Stew
• Sneech: Onion gratin soup | French Onion Soup
• Lumis: Tomato | Turnip

• If you don't have any specific gifts for them, spam Animal Treats, as everyone likes them with 1 heart.
  
  Additionally, the Bulletin Board (unlocked around Day 4) features the villagers' requests under the Local Board. Sometimes, you'll see items requested that are inaccessible or very rare (due to RNG). You can leave these unaccepted/cancel them by talking to the villagers. Once a new day rolls in, you'll get a new set of 4 requests from the board. You can accept and hold a request for multiple days in anticipation of getting the ingredient (e.g. Cherry from the tree). Since you can only have 4 active requests at a time, just complete whichever requests you can for the day to make room for the remaining requests from the board. Note: the Time TV at home has the same features as the Bulletin Board. Use this to your advantage to plan out your route for the day.
