the deal with "parasocial" relationships with fictional characters is that you have to "spend time" with them outside of their source material. this can be imagining scenarios, roleplaying with yourself, reading fanfiction, whatever. you have to assign her consistent personality traits you think are fitting in order to flesh out her character, because if all you're doing with her is wanking, that's all she's going to be. throw in a few arguments and situations where you need to comfort her/vice versa so you can feel like you're really developing a relationship. as cringe as it is we're probably going to be virgins forever so pillow kissing is not off the table. rinse and repeat to have a friendship or romantic relationship with literally any character and you'll never have to talk to real people again kek
