There’s a lot

• Harley & Ivy below Marceline & Bubblegum
• She-ra and Catra right outside
• Jinx & Lux (I think?) next to Vi & Caitlyn
• Charlie & Vaggie
• Ruby & Sapphire
• blonde girl I think from the isekai where the MC wants to seduce the villainess

I don’t recognize the couple right next to Harley (Ellie?) or the ones behind the counter

I spotted She Ra PoP (Catra and Adora), Owl House (Luz and Amity) and Stephen Universe (Sapphire and Ruby)

Edit: Harley Quinn & Ivy, and Charlie and Vaggie from Hazbin Hotel
