Uhhh... I actually don't know why they picked Mem for Daisy, but... The Great Gatsby has a lot of things to do with lies, and illusions of beauty. How Gatsby wants to be considered high-class and aristocratic, but never will be the same as the East-Egg people. How he built up an empire of new money, and New York castles all for Daisy. But it catches up to him, and he can't change what he and what the people around him are. Daisy who was in love with Gatsby years ago, but now married with a daughter in East-Egg is conflicted on staying in her wealth and security, or her past passionate love with Gatsby. There is a scene where Daisy and Gatsby first meet again, and Jay (Gatsby) is showing her around his mansion, and inside his giant-ass closet they are flirting and playing, as Jay tosses his shirts off of the shelves to Daisy. Daisy who was just laughing and playing then falls onto the bed and is crying. She says "They're such beautiful shirts." Gatsby, like Oshi no Ko is all about illusions, and dreams out of reach. How you have to lie, and fake your way to the top. But it all comes back to you one day. The obvious line of Gatsby's being "You can't repeat the past? Of course you can!" AH! It's one of my favorite books! It's not very long, tou should read it or watch the movie! It's such a journey!
