if im being totally honest, its the ENTIRE lore....!!!!! when i first start writing it, things were really simple mostly because i didn't intend to put sm effort into Leada (or more like Leada consumed my brain n i had no other choices) and there was only Ada and Lea being colleagues/partners and then falling in love. Not to mention Lea wasn't an absolute girl failure back then, so after that Dan helped me a bit w/the lore, making it more spicy and stuff 🐶 piecing the whole Leada first meeting together and Leada reconciling in re4 was super hard too considering I wanted to stick close to RE canon lore
