Wait, so we're seriously doing a re-run of the actual My Hero Academia, but with our OCs instead? Deku will be there to protect the 1-A students, and unlike All Might, he doesn't have that kind of terrible injury holding him back from being the best. I think we should try a different plot. Yeah, the exercises should be the same, but the New League of Villains, probably formed by international combinations of villains (including the one who poisoned Sylvia) should have a different agenda.
For instance, what if they interfered with the villain-hero training exercise in 1-A and since Jack will assist Deku in keeping the peace, they have to use Sylvia as leverage? I know I'm kinda drawing a lot of attention to Sylvia, and usually I try to blend with everyone, but Toxic (the villain from America who poisoned Sylvia) would have probably held a grudge against the targets who got her locked in prison, and knowing how close of a family they were, she would probably use her previous victim to get what she and the rest of the team wanted. I'm sorry this is how I'm doing it, but I also feel like this way, Classes 1-A and 1-C can connect and help each other help each other out, if you know what I mean. And, surprisingly, it'll bring Sylvia closer to being healed, too. What do you guys think? It's just a thought, and you're free to say no to it if you don't like it.
EDIT: Also, you don't all have to have a romantic partner. Sure, it's cute, but if you don't want one or don't really need one, then don't get one. Even if someone isn't good for you, you could probably make your own OC and match them with your original one... or something, idk.
