Thank you so much!!Immersive Shane apparently does a big improvement on him, but I haven't tried it or married him. Sebastian has a 7-event post-marriage arc which involves his family and his relationship with the farmer both. It's a bit talky but cute.
I know Abigail doesn't really have any post marriage mods (or even really any exclusive dialogue mods). Leah has a post marriage dialogue mod but none pre marriage and I don't think any new events. Elliott has at least one plus an extra event adder.
On Nexus, there’s a mod for Sebastian called ‘The Only One For Me’, which has added events, a couple edited vanilla events, and overhaul to Sebastian’s story and dialogue. It’s rather immersive and very well thought out. That mod is actually my inspiration / the reason why I decided to work on/create my own mods.Without I’m leaning towards Leah or sebby strictly but my curiosity gets to me with others creativity regarding mods thanks! :)
