You felt a soft smile on your face as you see Atsushi sleeping soundly on the agency's couch after a difficult mission. You decided to approach him quietly so you don't wake him up and you kneel down at the height of the couch and his face with the most sweetest smile on you face. You would've kissed him in the lips but you didn't want to wake him up so you just rested your head on his chest while playing with his hair softly so you don't wake him up from his sleep
