Complicated
Their friendship was complicated, especially with the longing yet uncertain glances he threw her way when he thought she was distracted; he constantly lifted his head, directed his gaze toward her, stared, then promptly looked away when she slowly turned in his direction.
She smiled, completely amused by his nervous actions, by the blush flourishing on his cheeks, by his shy, timid grins.
When she tutored him, he stumbled over his words and flushed. She beamed, entertained by his gawkiness.
"Sam, we're always going to be friends, right?"
"Of course," he responded; his voice was quiet and raspy, clogged with nervousness and awkwardness.
She smiled, completely enthralled by their budding yet complicated relationship.
