Natsume was always worried about you, since he knew about your obsession with doing your work perfectly, even if your health was at the risk, you'd still work until it's done. He didn't believe your promises anymore, knowing you'd get back to work once he's out of your sight.

One day, you were working again, not noticing anything, until you felt someone's hands in your hair, tilting your head upwards. "Next time you'll overwork yourself like that, I'll strangle you with my lips."
