Kantrip’s mature version of Sebastian

🎮 **An NPC module that allows you to get to know Sebastian again**

🌟Mod Overview

What if Sebastian was Robin's brother? What if he followed his dream and moved to Zuzu City to start a new life?

**What if everything goes wrong? **

Sebastian returned to Pelican Town and lived with his sister's family in their basement. He faces a new set of problems - rent, ongoing tensions with his brother-in-law and uncertainty about the future. He has new relationships, new conversations, and many past experiences that haunt him. He's still the same person...but not quite.

✨ Latest update v1.3

Welcome to the detail fix patch! Fixed a lot of small details that bothered me and players, and polished some more rough edges. If you're playing SVE, Demetrius no longer stands in the fountain for his 2-heart event; all outdoor events have been (hopefully) protected from vegetation and clutter, and I even removed the bong from Sebastian's spouse's room.

📖 Story background

**Mature version of Sebastian** is an NPC module of the original character in Stardew Valley. It updates all of his original dialogue, adds hundreds of new lines of dialogue (including after marriage!), adds 20+ new events (both before and after marriage), and adjusts his relationships with other SDV characters.

The mature version of Sebastian is in his thirties and has had a pretty rough life, including some time in jail (he hit someone with his car).

⚠️ Content description

**This mod contains some darker themes**, mainly drug use and unwanted pregnancy. You can disable some of the more serious events (labeled "black events") via configuration changes, and the mod will provide alternative versions of most events.

However, I highly recommend turning on the Black Event to get the most complete, mature version of Sebastian's backstory. Additionally, Sebastian's marriage dialogue contains some mildly suggestive content, which can be turned off via the "Clean Marriage Dialogue" setting.

🔧 Compatibility Notes

  • **Stardew Valley: Expanded Edition** - For SVE, I disabled some events and some schedule changes. No big deal, but should help with compatibility
  • **Immersion Spouse** - Schedule changes have proven to be less stable. I've made a few changes in v1.1 that hopefully resolve some of the issues people are having

💎 Recommended combination

For the best experience, I recommend using the following together:

  • **DCBurger's HD portrait** + **OrangePie's short-haired Sebastian mod**
  • **Secret Notes Framework** - Custom secret notes for displaying a mature version of Sebastian
  • **WEDDING ANNIVERSARY** - for custom wedding anniversary texts and unique gifts from the grown-up version of Sebastian
  • **Portraiture** - Portrait display tool

📝 IMPORTANT NOTICE

The Seven Hearts Event is the first "black event" of the module. If you want to see this event, you need to **not start dating Sebastian** until you see this event** (and make sure black events are enabled via the config file). Otherwise, you will trigger the Eight Hearts (white) event.

Install & use Install: SMAPI mod (Stardew Valley standard)

  1. Install SMAPI first (Stardew Valley's mod loader): download it from smapi.io, run 'install on Windows.bat' and pick your game folder.
  2. Unzip the archive from playbuff and find the folder that contains manifest.json — that folder is the mod.
  3. Copy that whole folder into Stardew Valley/Mods/.
  4. Launch the game through SMAPI (run StardewModdingAPI.exe or set it as the launch option). The console before the title screen lists each mod's load result.

Cheat-style tools may not need SMAPI — unzip and run them as the readme describes. Back up your save before editing it; SMAPI lists failed mods in its console.
