Sleep has never been on my schedule

Espresso hunched over his work desk, eyes scanning over the blueprint frantically. He sighed in defeat, still not being able to find the part of his work that could make the whole thing collapse on itself. He took off his glasses and pinched the bridge of his nose, trying to relieve some pressure from his mind.

Or alternatively - Espresso has been researching things for his project for over 72 hours, his only fuel being lazily brew coffee and leftovers from who knows when. To his luck, Madeleine comes around to check on him and (lovingly) forces him to get some rest.
