Marco might argue this point - he's pretty sure he did something wrong here! - but he doesn't try to right now. No, he knows enough about Jean to appreciate the fine distinction he's asking for.

He wants Marco to want him, not do it out of an obligation. Marco knows he's not, so he has to tell him that.

"I want to," he tells Jean when he sits up. He, very slowly, so Jean can pull away if he wants to, reaches out to rest a hand on Jean's arm and squeezes, his cheeks flushing a bright red.

"I wanted to offer last time, but I couldn't." No, Jean had been whisked away too fast, and Marco was just barely blooming into being a beta at that time. He's not sure he would have had any idea what to do, and they probably would have ended up frustrated.

... Not that he has a plethora of ideas available now, but he at least understands, thanks to their classes, what Jean needs.

His last words are quieter, tucking his own chin into his chest - a sign of submission to Jean. "You always smell good. I was happy we got to practice today."
