Natsume never showed his own stress or any unpleasant feelings to you, not wanting to worry you, but, even someone like him wanted to just lay in the comforting embrace of his loved one, although he didn't tell you that. One day, he looked really stressed, and was looking really tired. As he saw you just laying here with your eyes closed, he just laid on top of you, hugging you close to himself, as he nuzzled his face against your neck.
