Oh cool. I do have ideas but I'm terrible at writting in english.
Ideas:
#1 A restless reader can t seem to fall asleep and our special assassin enters her room at night to maybe just cuddle to help fall asleep.
#2 It's winter and reader is cold, maybe they could enjoy a nice cup of tea in front of a fireplace. (and cuddle)
#3 There's a thunderstorm (I hate those T.T) and our assassin comforts poor reader with a lullaby (and cuddling...always the cuddling lol)
So feel free to message me if you ever write any. By the way I speak french so if you need translations for Arno, just ask
