Naturally! And Izuku has an idea!

"It's more than that, too... even sexually speaking, you treat us all pretty differently, according to our own preferences," Setsuna smirked as she leaned into Izuku's side. "There's a different dynamic between each of us and you. Some similarities, sure, but overall different. Like the fact that, despite the fact that you could have easily used Momo's powers to make me your sex **** like the others, you instead opted to let me into the harem on as equal footing as possible with you. While you're ultimately still in charge, given that you have the genie, I get to dominate the other girls, and don't have to submit to you sexually. Like I said, we all have our own special dynamics," she finished.

"...wow, that's pretty deep," Izuku chuckled and she huffed and punched his arm.

"I'm not just a pretty face, Izu-kun," she pouted. "...definitely that too, but not just it."

"You could literally become just that though," he teased, referring to her ability to detach parts, and she laughed at his comment.

"You got me there... but I also enjoy your wit, and willingness to engage in petty **** wars with me," she added. "You certainly do a good job building up a relationship with each of us in a way that allows us to coexist within our little group. Hell, not just coexist, but get along like besties," she noted.

Izuku nodded, and then had a thought. "You know what, you're right, I am the one with a genie," he remarked. "That does mean things are a bit further from equal than they should be... how about we correct that a bit?"

Setsuna blinked, and followed Izuku as he started walking, looking for Momo. "You got something in mind?" she asked him.

"Yeah, I do," he grinned. Setsuna considered inquiring further, but he didn't seem to want to spoil the surprise, and as far as his ideas went and how she liked them, he had a great track record.
