(Security Office)
This game is basically a prequel to INHEAT Lustful Nights. In Sammy's Circus, we see that it is poorly run down as if something bad has happened. In Honeymoon, Ari tries one of the alcohol chocolate treats and goes on a full rampage killing someone. Thats why Lustful Nights, in Nile's Restaurant we see a dead corpse lying in Nile's Restaurant. (the table cloth on the floor covering the body)
(Lustful Nights) The room where Sammy usually sits/stands at the beginning of the night, there is a wanted poster of Poppi on the far right side of the camera. Well, in the Honeymoon, She snuck in the factory for fireworks and wanted to blow up the whole island.
Some other lore you might find. Misty in Honeymoon being in the pool, which is just located outside the Nightclub & The Security Guard in Lustful Nights is just an employee staying over in an apartment complex.
When opening the menu screen in the original Lustful Nights, You seem to be staying overnight in the Diamond Straits Resort.
