The player can form a bond of friendship with townies, giants and merfolk (merfolk currently not implemented). The better the player gets to know the them, the more stories and dialogues the player will discover. Friendship does not decay over time.
Currently, player may eventually gain heart level when chatting with some strangers as well without any seen impact.
Heart points[]
The player's 
heart points, or friendship points, with a character is represented with a heart gauge that gets filled over time as the player talks to that character and gives them gifts.

While regular characters have max heart level of 10, dateable characters will have their heart maxed at level 8. To unlock max level up to 10, they need to be dated by giving them Locket. Multiple characters can be dated.
Further, once the dated character is wed, the max heart becomes 15, and currently there can only be one spouse.

Heart events[]
Gaining heart level with each character will unlock unique events. The event triggers and conditions vary depending on the character. Refer to each character events information for more details.
Earning heart points[]
The player can earn Heart with characters by chatting with them daily and giving them gifts.
Chatting[]
The player can chat with each character to get 35 Heart per day. During festivals chatting may earn 0, 35, 50, or 85 Heart, if they haven't talked on that day yet. The player can chat with a character as many times as they want until their lines for the day are exhausted without earning more points for that day.
The characters have a variety of lines they can give to the player: generic lines, the lines specific to their current location, the lines specific to the current season, or the lines specific to their heart level with the player. The characters can give their reactions to some in-game story events like the arrival of Pufferfish Drilling Corp into town or the Museum expansion. Some characters will also comment on the player holding a weapon in their hand or wearing a Pufferfish farmer outfit, a Chicken suit, a Panda outfit, or wearing no clothing at all. Additionally, there is a small chance to hear the characters slip up and give rare dialogue lines that are often very personal and non-repeatable.
Hangout[]
The player can ask certain characters for a hangout while their hands are empty. The hangouts can be normal hangouts or dates with romantic interests. Some hangout locations have weather requirements or need to be unlocked for the player to visit them.
Gifting[]
- See also: Gift preferences page for a sortable list of all characters and their individual gift preferences
Gifting is a primary mechanic of earning Heart with characters. The player can give each character up to two gifts per one in-game week (plus one additional gift on a character's birthday). In order to gift an item, the player needs to place it in their inventory hotbar and interact with the character they want to gift the item to.
Most items in the game, such as scavengeables, crops, fish, insects, artisan products, meals, and even trash, can be gifted. Each character has their individual gift preferences: they can love, like, dislike or hate the gift, or have no reaction to it. Characters will have different interactions with the player based on their preference towards the item. The more the character likes the gift, the bigger the Heart gain. Dislike and hated items on the other hand have minus Heart gain, however it will never go beyond the current heart level, or in other words, heart level won't decrease. Example after table below.
Gifting points[]
| Gift preference | Points |
|---|---|
| Love | 140 |
| Like | 70 |
| Neutral | 35 |
| Dislike* | -35 |
| Hate* | -70 |
*For example the player has reached 4/heart level 4 with Ben and is having 1550 Heart
Item multiplier[]
On top of that, there is a multiplier if the item has better quality.
| Item quality | Multiplier |
|---|---|
| Bronze | 1.15x |
| Silver | 1.3x |
| Gold | 1.5x |
| Osmium | 2x |
Note that fractions will be rounded down.
Birthday multiplier[]
It doesn't stop here, if it's given during a character birthday, it will be multiplied by 5. Meaning, if it's a loved item, osmium quality, and given during birthday, 1,400 Heart will be earned. Do note some characters do not celebrate birthday, so the birthday multiplier isn't applicable for them.
Errands[]
Townies may randomly request for errands. Completing the errand will earn 250 Heart with that character. See Errands.
Events[]
There are certain milestones that provide Heart to all townies. However these points won't be retrospectively added to townies the player haven't met. The points mechanics will be revisited once merfolk friendship is available to check whether those are awarded to merfolk as well. Currently, Giants are not affected by these points

Quests[]
Some minority of the main quests also provide Heart to certain character upon completion.
The mail side quests will set the heart level to 1 with 300 Heart towards the requestor when the heart level is 1 or below. Meaning, if the friendship points are below 300 it will be boosted to 300, reaching heart level 1, however, if the friendship points are already reaching the next level, e.g. 630, it will reset back to 300.
Romance[]
Players are able to date and eventually marry one of the 25 dateable characters and start a family with them. In order to do so, players must reach a certain level of friendship and unlock the character's story. Romance is not restricted to any gender.
