You'd be close! The four planned arcs are:
- Janitor
- Security
- Counselor
- Ambassador
The main base game will likely end with the Counselor arc, with the Ambassador arc as expansions. The way we planned it out, each world you'll be able to visit should have its own expansion with its own roster of love interests. I dunno how REALISTIC that vision is, but that's what I'd LIKE to do lol
