As a lesbian, their relationship meant the world to me. It felt incredibly natural and reminded me of a lot of my relationships incl. my current one. It's not only the dialogue, but especially the little glances & touches, the body language that does a lot for me & other lesbians I know. There's so many little things. I genuinely can't explain it, but it felt so incredibly loving, tender & intimate. Something we sadly aren't often allowed in media. Was the relationship & their portrayal perfect? Of course not. But I can't think of many - if any - that were handled better & with more care. I adored their playfulness too - you can't forget they're barely of age, they're not a boring 30smth cishet couple for who it's just all the same or however you wanna say it. They're young, they're excited, they're just being silly sapphic women in love. Ellie especially is just such a useless lesbian around Dina for a while, it's beautiful & reminded me a lot of myself. Also crazy to me that people feel like they were too loving when that's how I act with my beloved. Some people are very affectionate all the time & aren't scared to show it, it's okay.
EDIT: Also, the game made me want to pick up playing guitar again, even though I suck so fucking much at it. But if I won't be able to serenade my future wife at our wedding I might as well die now. Also, this thread reminds me that I desperately need to play Fatamoru.
Can only speak from my dating experience, but that's how a lot of lesbian & in general wlw couples flirt, especially at the beginning stages & if they're younger. It's cute and stupid, but I adore that. It's playful when it needs to be and serious when it needs to be.
