At the crack of dawn

Chad wakes up and so does Isabel, both still really happy about last night. Chad realized he was still a man and was now confused why the effects haven't worn off. They both got confused and then both said "Why am I still like this? Gasp. What! Youre?" Chad then realized that it was him, Isabel Maria was deep down Izuku Midoriya. "Wait, Deku". "Uraraka, wait"

"How do you know and how are you like this?" Isabel answered right away "After you left, I went to see if you left anything important. Then i saw the pills, I took one because I thought it was candy, but I turned into a girl. I then realized you were Chad right when I saw you". Chad then asked "Why change again?" "Because I love you. I thought that you were now interested in girls, so I took one to make things work between us".

Chad explained "I only got attracted to girls because of a side effect of the pills. I started taking more because of how much better I felt. If you still want to be together, whichever works for me". Isabel sighed and said "of course I want us to be together". They kissed again and sneaked into Chad's room.

"We need to figure out why we haven't changed back, were happy and we didn't take another pill". They both looked at the note.

If two people with quirks using X-change have sex, the effects will stay for about a week.

"A week!" They needed to figure something out. "I got an idea, for both of us". Isabel said.
