"Just a bit longer..." | Relationship/Roommate!AU

Scenario: You've been living with Kanade for a bit. You've been dating her for longer. You've gotten used to her tendency to work herself to the bone, even. But...today's too much. Too worrying, for too long. Even after you ask her to stop, even for just a bit, she...refuses. She wants to keep composing for just a bit more, just a second more.
