Starsand Island Romance Guide: All 15 Partners, Dating & Move In
Last updated 2026-08-25 · Based on version 1.0 and community sources — items marked “TBC” are awaiting verification.
Starsand Island has 15 romanceable NPCs (8 women, 7 men). There is no traditional marriage system: the relationship endpoint is Move In — at 5 hearts you can invite your partner to live with you, which functions as the game's equivalent of marriage. Romance is fully open regardless of your character's gender, and every candidate has official 3-heart and 5-heart story events. One exception: Youfang can be romanced but is currently the only partner who cannot move in.
All 15 Romanceable Characters
The list below matches the official Heart Events guide and is confirmed across community wikis:
| Bachelorettes (8) | Bachelors (7) |
|---|---|
| Solara — Community Center guide | Zephyria — Exploration Club leader, Exploration Mentor |
| Zerine — General Store owner, Crafting Mentor | Delphin — AquaBlue Outpost, Fishing Mentor, surfer |
| Pastelle — Green Pasture Ranch, Ranching Mentor | Graminova — Happiness Seed Shop, Farming Mentor |
| Lunelle — Ethereal Styles clothing shop | Aurelis — Aureleaf Kitchen chef |
| Serena — Bloom Atelier stylist | Sylvain — Silvan Notes music shop |
| Stella — Woof & Wow Pets owner, idol | Loren — Chrono Arcade owner |
| Neona — G-Power Bikes owner, rider | Youfang — Bastrom Heights diviner (no Move In) |
| Alex — Lex Woodworks carpenter |
Same-sex romance is fully supported: two independent guides confirm the game places no restriction based on your avatar's gender — all 15 candidates are available to everyone.
Affection Levels: What Each Heart Unlocks
- 1❤ Acquaintance — the NPC starts giving return gifts.
- 2❤ — you can invite them for photos together.
- 3❤ — enter their room; unlocks their 3❤ story event and dating.
- 4❤ — post Bulletin Board requests for them; they can Follow you (share a bench, ride together).
- 5❤ — unlocks their 5❤ story event and Move In.
Points needed per level, per a community guide the official subreddit's pinned guide list recommends: 90 to reach 1❤, then 220, 370, 770, and 750 more for each following heart (the last two figures are single-source (TBC)). Earning points: daily chat +5, daily gifts (+10 liked; favorite gifts recorded as +15 or +25 depending on the source and version (TBC)), bulletin requests +15–25, returning lost items +20, quests up to +50, and completing a date +35. Giving a disliked item can reduce affection. The phone's Social app shows exact points and each NPC's recorded gift preferences.
Heart Events: 3❤ and 5❤ Story Quests
Official mechanics: each candidate has a 3❤ and a 5❤ story quest. After you reach the required hearts, the quest triggers the next day — usually by mail (sometimes sent by a different character), though Zerine's and Pastelle's 3❤ events trigger by visiting a location instead (Zerine's Basement; Green Pasture Ranch). The 5❤ quest requires finishing the same character's 3❤ line first.
Standard rewards: 3❤ = 700 Coins + 50 Starsand + 60 affection with that character; 5❤ = 2,000 Coins + 100 Starsand. A few have extras: Loren's events add arcade Tokens plus his championship photo, and Lunelle's 5❤ event ("Beneath the Stars") rewards a full outfit set for both body types. Some memorable quest names: Zerine's "Unit 01's Confession," Delphin's "Azure Guardian," Graminova's "The Only Variable," Sylvain's "Moonlight Sonata," and Stella's "Starsand Island Rock Band." The complete per-character quest table is on the characters page.
Dating
Dating unlocks at 3 hearts (a community rumor said 5 — guide authors tested and debunked it). Interact with the character and choose "Date," then pick an activity and location; options vary by character. Date locations fall into three groups — picnic spots (lighthouse, flower corridor, mountain), entertainment (arcade, music shop, hot springs), and cafes (Soluna Cafe Lodge, Aureleaf Kitchen, beach bar) — and each of the six officially profiled candidates has documented favorites (e.g., Zephyria and Delphin both favor the lighthouse, hot springs, and beach bar). Dates are limited to once per week per NPC, and can't start after 21:00 in-game.
Timeline note: when dating first launched (April 2026), only six characters could be dated — Solara, Zerine, Pastelle, Graminova, Zephyria, Delphin. Version 1.0 expanded the dating system with new activities (picnics, arcade challenges, kite-flying) and added "relationship stories" from 3❤; whether all 15 are now datable hasn't been explicitly confirmed in patch notes (TBC).
Move In: the Game's "Marriage"
At 5 hearts, interacting with a partner offers the Move In option. Key facts:
- You confirm manually, and your house needs enough space before you can invite them.
- You can raise several characters to 5❤ simultaneously and then choose one to move in.
- Youfang is the sole exception — romanceable, but Move In is not currently supported for him.
- Player reports say the partner takes several in-game days to actually arrive (one player waited about two weeks — anecdotal).
- There is no proposal item like Stardew Valley's Mermaid's Pendant in any known source; the mechanic is simply the 5❤ dialogue option.
Will traditional marriage or children be added? Community reports of developer statements conflict — some players relay "no marriage/kids planned, but NPCs can live with you," others say it may come after 1.0. As of the 1.0 launch, no official announcement confirms marriage or children; treat anything else as rumor.
Practical Romance Tips
- Front-load affection with the right gifts — see the gift guide for every candidate's loved items and the safe universal picks.
- Do heart events promptly: the 3❤ event alone grants +60 affection, accelerating the climb to 5❤.
- Note for multiplayer: the Date function is locked during multiplayer sessions, and affection earned as a guest syncs back to your own game afterward.
