Natsume was always acting slightly reserved with you, not interacting with you unless needed. You didn't blame him, maybe he needed time. But you always felt someone kiss your forehead while you're asleep. You were in your room one day, until you heard Natsume entering the room and walking closer to you, before brushing your bangs off your forehead and giving you a kiss. No hesitation whatsoever. He knew you were aware of his presence, so why not?
