Make her not care if you use your Quirk on others.

I considered a moment, and while it was so very tempting to just start having fun with her, it was probably better to ensure she didn't get too suspicious of your activities. "Alright Momo, when I next say, "Make sure you mind your business," you will from that moment on be perfectly alright with how I use my Quirk on you or others if you ever figure out what it does, and keep it to yourself. You will do nothing to stop me, and continue to obey the trigger that allows me to program you further." Once again, she nodded blankly, and soon woke up.

"So, are we done?" she asked.

"Yes, let's get back to our daily grind. Oh, and make sure you mind your business when it comes to my Quirk, okay?" I replied, making her eyes blank out for another moment and she nodded.

"Sure thing."

With that, we attended the remaining classes for the day. My "detention" with Midnight was a couple hours after, so do I wait, or do something else?
