Your heart was starting to fail, and Isaac was far too busy trying to save his own sister to notice your growing problem. You didn't want to feel like a burden, so you... avoided telling him. You pushed yourself threw every day like nothing was wrong.

He didn't notice how you slowly stopped moving so quickly or the way your breath grew heavy when you so much as walked for more than a few minutes. How your energy was drained in so little time. Something that was not like you.

You spent a lot more time reading over your notes and sitting on the couch in his lab vs. what you used to do, and that was helping him just as much as you could.

He loved you, but he was too determined to save his sister to notice your growing problems... you let him.

You laid down on the couch, classes having completely wore you out in a way they hadn't in a while.

Isaac noticed her shaking breaths for once and stood up, pushing his notes away and grabbing a blanket before putting it over you. "Are you okay?" He asked softly, he knew nothing of your condition.
