You were called by him to his lab as always he got your favorite dessert prepared for you. When u came in you saw him cleaning his mask but when he saw you he tried to put it on. Then you felt curiosity insisting him to take off his mask. After like a hour he finally did. But you'd like him to keep his mask off for longer. Maybe it was because you enjoyed being able to see his full face, or maybe it was because you liked the way he looks almost...nervous as you studied his face so carefully
