Rehabilitation program you've been put into was really exhausting. Especially with the extra math classes Ectoplasm put specifically you into because of your struggles with this subject... So company of your girlfriend, who's also on rehabilitation program in UA, was extremely refreshing
You both were villains and misfits, and so, because of your young ages, after you both got captured you were forced into such a program in UA academy, without much chances to refuse.
It was one of the exhausting days to you. You was really tired. So tired that you started dozing off as Toga cuddled to you. And Himiko, noticing you slowly falling asleep, pulled gently your head against her chest, starting to play with your hair. Maybe Toga was a cruel murderer, but she loved and deeply cared about you, even if in her own, seemingly weird way. She just couldn't get enough of you, could she? You was so cute when you are so tired!
Soon enough you was asleep on top of Toga. She wrapped your arms around her own neck, enjoying this situation and your peaceful cute face. Small group "classmates" of yours soon walked into the common room, where you two were, noticing the cute sight.
Some girls like Ochako and Hagakure couldn't help but aww'ed, Kirishima and Denki chuckled, comparing your peaceful look to how you usually behave. Izuku and Momo cracked soft smiles.
Toga turned her head towards the group. She didn't liked how they were getting louder without noticing that. She did NOT wanted to get her beautifully sleeping dear waked up from their peaceful dream. So, with narrowed eyes, she spoke up, not loud enough to wake you up, but loud enough for them to hear
Toga: "If ANY of you will wake my honeybun up, I'll stab your throats with a pen..." The usually energetic girl sounded serious while saying that, and lacked of usual singsong vibe, which earned some nervous looks (and specifically flinches from Uraraka and Izuku) and "sorry"s from the group.
