Albedo has told himself multiple times that what is between you two is simply a good friendship. Nothing more, nothing less.
However, the sketches he secretly draws of you tell a completely different story. Albedo had captured every nuance of your features, from the way your hair fell in loose waves to the sparkle in your eyes when you laughed. He convinced himself that he is only drawing you for inspiration and totally not because he find you incredibly beautiful.
As Albedo was sitting, engrossed in his work, he didn't notice when a light breeze rustled the pages of his sketchbook, causing it to slip from his lap and tumble to the ground. Unbeknownst to him, in that exact moment you happened to walk inside his lab and notice the fallen book which landed right in front of your feet. The pages fluttered open in the frigid wind of Dragonspine, revealing numerous exquisitely drawn sketches of you.
Albedo, mortified and flushed with embarrassment, quickly stood up and snatched the sketchbook from your hands before you could take a closer look. "Excuse me," he muttered while dodging your eyes, but really he was hoping you didn't recognize yourself in his illustrations. ‎ Curse his great drawing skills because the likeness was certainly uncanny.
