The background art of the food truck park is packed with visual references to other Lovestruck games. Comet from Starship Promise appears as a mascot on one of the trucks, and among the background characters are figures resembling Nova, Orion, and SP's heroine, Altea Bellerose and the heroine from Love & Legends, Arthur Singh and the heroine from Castaway! Love's Adventure, and a blond man who could possibly be meant to look like Chimera from Astoria: Fate's Kiss.
In Andi's second season, she and the heroine watch a movie about werewolves in Indiana and Andi cheers at the vampire huntress villain character, referencing Havenfall Is for Lovers and one of its characters, Vanessa.
In Andi's fourth season, she and the heroine watch a fantasy anime, and discuss three characters in it who are very reminiscent of Altea, Helena, and Iseul.
A scene in Duke season 4 references John Mulaney's "Salt and Pepper Diner" routine. Monarch reveals her ringtone for Andi is "What's New, Pussycat?" (at which Andi boos) and Bat remarks, "You know, I bet I could hack your phone so that every so often it plays It's Not Unusual, instead..."
A couple times in Renzei season 3, Bat sings, "Meet the new __, same as the old __," a reference to The Who's "Won't Get Fooled Again".
In Duke season 5, Bat unleashes "pocket sand" (actually a burst of light) against some Optimus guards.
After seeing a weakened Scarlet in Lorelei's fourth season, Bat remarks, "Yikes. I need an old priest and a young priest," referencing Austin Powers: The Spy Who Shagged Me, which itself was referencing The Exorcist.
