Revision 4

How relationships work

Relationships use a heart-based affection system. Each character has a friendship meter that fills as you interact with them. But unlike most life sims, gift-giving is not the only (or even the best) way to raise it.

NPCs observe what you do. They notice who you help, what you say, what gifts you give, and who you spend holidays with. Your actions shape how they feel about you. This goes beyond standard fare. The NPCs have a memory system. They remember past interactions, reference things you have done together, and their behavior changes based on your history.

Five relationship tiers

The relationship system has five named stages. Each one unlocks new interactions:

1. Gifting -- You have just met. You can give gifts and have basic conversations. This is where everyone starts.

2. Outing -- You start spending time together outside. Activities like bike rides, park visits, and group hangouts become available.

3. Room Visit -- They come to your house. You visit theirs. The conversations get more personal.

4. Requests -- They start asking you for specific things, favors, and help with personal problems. These tie into their Heart Story.

5. Cohabitation -- They move into your home. This is the final tier. There is no marriage mechanic in Starsand Island. Cohabitation is the equivalent.

The pace depends on how much time you spend with the character and how your interactions go. You cannot brute-force it with gifts alone.

Heart Stories

Each of the 12 romanceable characters has a personal storyline called a Heart Story. These unlock as you progress through the relationship tiers. Heart Stories have branching endings based on your choices during key moments, so two players dating the same character might get different outcomes.

These are not short cutscenes. The Heart Stories develop across multiple in-game days and involve specific quests tied to that character's background and personality.

NPC behavior and memory

The NPCs take autonomous actions as your relationship grows. At higher affection levels, a character might:

• Write you a love letter

• Give you a gift unprompted

• Start addressing you with more familiar terms

• Visit your house to hang out

• Comment on changes you have made to your farm or home

• Reference things you did together in the past

Relationships do not feel like a one-way street. The NPCs initiate things on their own, which makes the system feel more alive than the standard "give gifts until a bar fills" approach.

Signature activities

Each character has activities you can do together as your relationship grows:

• Fortune teller readings with Youfang

• Riding bikes together

• Swinging at the park

• Having sleepovers

• Binge-watching TV on the couch

• Cooking meals together

Each character brings their personality into the activities. Spending time doing these things raises affection faster than generic interactions.

Tips

• Pay attention to what each character likes. Their preferences come through in conversations.

• Participate in seasonal events with the person you are interested in. NPCs notice who you spend holidays with.

• All 12 romanceable characters are available regardless of your character's gender.

• There is no marriage. Cohabitation is the final relationship tier.

• Heart Stories have branching endings, so your choices during key moments matter.

• Gust and Ginger (My Time at Portia crossover) are not romanceable but can be befriended up to 4 hearts.

• Francis (your childhood friend) is not romanceable either.

• 2-4 additional romance characters are planned for post-launch updates.
