Harvest Moon®: Echoes of Teradea Sergei, marriage candidate
Last updated 2026-10-18. Checked against the sources below.
Sergei is a base-game bachelor in Maplehill Town. Birthday: Summer 20. Favorite gift: Wooden Planter. The first heart event requires 1 heart after Harvest Goddess Chapter 1. The tables below give Neoseeker's reported preferences and event triggers, recorded on 18 October 2026.
Birthday and gifts
| Detail | Reported value |
|---|---|
| Birthday | Summer 20 |
| Favorite | Wooden Planter |
| Liked gifts | Mountain Lotus, Energy Juice |
| Disliked gifts | Crucian Carp, Tofu, Doria |
| Source | Neoseeker: gifts and birthdays |
These are item-specific preferences, not blanket rules for crops, flowers or fish. Neoseeker reports one gift per person per day; liked gifts give twice the friendship of a neutral gift, favorites three times. On a birthday, a non-disliked gift counts as a favorite. This is guide-sourced data, not our own playtest.


Six heart events: requirements, locations and times
The first event opens after Harvest Goddess Chapter 1, not simply after meeting Sergei. Neoseeker says each new heart level sends a letter and further friendship waits for that event. Read the letter, track its request and follow the musical-note marker.
Events 1 and 3 start by talking to the candidate. The other rows are meeting triggers, not the destination of every scene. For events 5 and 6, first give a Token of Love after event 4.
| Event | Requirement | Trigger location / action | Time |
|---|---|---|---|
| Heart event 1 | 1 heart; after Harvest Goddess Chapter 1 | Talk to Sergei | No separate time window listed |
| Heart event 2 | 2 hearts | Under the Maplehill Spirit Tree | 06:00-23:00 |
| Heart event 3 | 3 hearts | Talk to Sergei | No separate time window listed |
| Heart event 4 | 4 hearts | In front of the Harvest Goddess Tree | 06:00-16:00 |
| Heart event 5 | 5 hearts; Token of Love | Maplehill town square | 09:00-16:00 |
| Heart event 6 | 6 hearts; Token of Love | Sergei's lab | 12:00-18:00 |
Source: Neoseeker: Maplehill heart events, read on 18 October 2026. Neoseeker says bad weather cancels most outdoor meetings; events 1-4 wait during festivals in this candidate's town, while events 5-6 wait during festivals anywhere. A row without a time is not proof of 24-hour availability.
Where to find Sergei outside events
Maplehill Town is the sourced home location. The event table gives specific meeting points and windows, not a daily walking timetable. Weekday, weekend, rainy-day and post-story routines were not verified in the sources checked on 18 October 2026.
Background and main-story appearances
Sergei is an inventor in Maplehill whose research is the mist and the other odd phenomena around Teradea.
The Maplehill walkthrough places him at the dinner party and at the restored Spirit Tree. Those main-story appearances are separate from the personal romance sequence in the event table.
Rules that apply to every candidate, including Sergei
- You can marry any candidate regardless of your gender.
- You cannot marry the protagonist you are playing. The other protagonist remains eligible: Robert when you play Carol, or Carol when you play Robert. That leaves 9 eligible partners from the 10-name roster.
- The ceremony itself waits until after the staff roll.
- Neoseeker lists a Token of Love after heart event 4, followed by events 5 and 6. Tiny crafts it at the Harvest Goddess Statue Altar using 10 Red Rose and 10 Diamond; the recipe unlocks the next morning after anyone's fourth event, provided Harvest Goddess Chapter 1 is complete.
- For a proposal, Neoseeker requires heart event 6, a Level 3 house, the Blue Feather from the end of Harvest Goddess Chapter 2, and no prior proposal to someone else. Hold the feather and give it to your lover.
Source checks
I read Neoseeker’s Maplehill romance page on 18 October 2026. Sergei’s first event waits for Harvest Goddess Chapter 1, unlike Bryce and Shirley. GamesHorizon independently lists Mountain Lotus and Crucian Carp as liked and disliked respectively. These details retain the earlier source reading from this date. A later HTTP recheck of the six Neoseeker references returned security-check pages (403), so that pass is not an independent confirmation.
