OVERALL

The figure's NPC is used in a few events. Its presence is supposed to be unsettling. There are smoking and non smoking versions of events.

SPECIFICALLY

• []The smoking version of the 1 heart event includes Sebastian smoking into your face with the non-smoking version of the 1 heart event includes Sebastian fondling a butterfly knife (get it ig)[/]

  []TW the 3 (Pt 1) heart includes Sam (fr tho: It's implied the farmer drinks and throws up, two men fight over you, and there's a brief stalker entrance (view this at fullscreen for the best experience frfr))[/]

  []The 3 (Pt 2) Heart is a HEAVY stalker mention; someone will break in if you don't lock your doors. It's implied you're asleep, but NOTHING HAPPENS TO YOUR FARMER. Just some cameras get fixed is all[/]

  []The smoking version of the 5 heart includes a shotgun kiss with the non-smoking version of the 5 heart includes sharing a lollipop[/]

  []For the 6 heart vanilla rewrite: refer to the DND Decision Branches photo[/]

  []The 6 (Pt 2) heart is an implied wet dream. The dream version of you touches him. A lot. Also ur a bit dominating here ;)[/]

  []For the 7 heart: refer to the CCTV Decision Branches photo[/]

  []For the 9 heart: you get pinned to a couch and potentially kissed depending on the route you take; you do have the option to deny[/]

  Is this compatible with...?

  For most dialogue mods it's an iffy thing. If you're placing in a dialogue mod for Sam, then yeah this one'll work fine. On the other hand, If you're placing in a mod for Sebastian, like some other Sebastian dialogue mods, then no. HOWEVER, in the config option there are options to turn off the dialogue/events if you prefer someone else's!

  AN IMPORTANT NOTE ABOUT COMPATIBILITY

  This modpack edits Sebastian's room & some room strings. This clashes with SVE's room changes. I
