FYI, GDD girls are named after real erogame maker.
Alice - Alicesoft
Yuzu - Yuzusoft
Seiba twins (Momoi and Midori) - Cyberworks (Wendybell and Tinkerbell)
I really wanted to talk about this to someone as soon as I learned the focus of the chapter is dating sim lmfao. I had a feeling they were referencing Alicesoft and Yuzusoft and I believe the 2 characters in question actually somewhat reflect the overall themes of both companies they are based on. Like say Yuzu, the timid and adorable girl who basically possess traits of vanilla moe type shit character in probably almost every Yuzusoft titles. Meanwhile our sweet and cheery Alice, let's just say that going by Alicesoft standards, there's more than meets the eye and it's not always butterflies and rainbows on the inside xd
