📋 About This Mod
WHAT THIS MOD DOES
I wanted my Seb to be mentally well but still have some spice and obsession. That's what I've made.
I edited a lot of the lines of Isa's work to make a "soft version"
that fit my idea of Seb, he's possessive, controlling and obsessed with
you.. but a lot less scary and a lot more romantic.
This is my first mod, and I just made it for myself. So please be nice. Oh and
it works for either gender!
Description
By "soft version" I mean he's possessive, protective, controlling and obsessed. In Isa's
mod there's animal cruelty, knives and he generally goes downhill
mentally when you come to Stardew Valley. I started to rewrite just a few things so it's a little less concerning and went a lil overboard and somehow it became it's own mod.
This mod is not in the horror genre: there
is no animal cruelty, no knives, and everybody just thinks he really, really
likes you. Maybe a little too much. It might be a bit obsessive but hey, romance novels and all that jazz.
There is special dialogue for receiving a bouquet, and a sweet surprise when you give him a
mermaid's pendant.
There's special festival dialogue, spouse and pre-marriage dialogue. Like lots
of dialogue, over 200 lines.
- over 200 lines of both pre-marriage and post marriage dialogue, and festival
- unique lines for when you've divorce or are rejected
by Sebastian
- Robin, along with bachelors and bachelorettes around Sebastian's age group
will comment on his behavior during the different seasons.
- unique lines for receiving a bouquet or a mermaid's pendant.
I forgot to take pictures so:
