No but like El will be happy about Byler. Like actually happy, not just okay with it. It's not just her who doesn't "get" Mike and his nerdiness and need to be the hero, it's also Mike who doesn't understand the depths of El's humanity despite being a "superhero" and all of the trauma she deals with and has yet to work through. Her uniquely feminine experience and all of the challenges and milestones that come alongside maturing as a young woman, which is something that Max understands perfectly well, and this is the reason why El has begun to prioritize her friendship with Max over her relationship with Mike. El knows in her heart that she and Mike are already doomed romantically, I just think she was in denial about it until Mike's monologue. The only fear both El and Mike have now is that the absence of romance from their relationship means there won't be a relationship period i.e. they are destined to lose each other. For El, knowing and understanding that Mike is gay and in love with someone else and literally CAN'T be with her romantically will be the biggest signifier that they were never going to be able to hold onto that romance in the first place. Now they can work on being friends. If anything it's Will who's going to struggle to be with Mike in light of the guilt he will feel from "stealing" Mike from El, and I wouldn't be surprised if El is going to be the one to ultimately push Will towards Mike and encourage the two of them to be together.
Bro I just remembered last year when my friend and I were deep in the byler era and we passed little papers saying "byler endgame" or "emagdne relyb" to the people sitting behind us in class 😭
