Tonight after putting your son to sleep you waited for Mattheo in the living room, he arrived around 2 am.
"You're finally here" you said seriously, looking at his neck, which had marks that you hadn't made
"I thought you were sleeping,
"What are you doing awake?" He came closer to kiss you but you moved away
