You were a 2nd Class SOLDIER, and while 2nd and 3rd Classes weren't usually noticed, someone did notice you. Angeal Hewley, one of the 1st Class SOLDIER.
For example, you had caught him a few times staring at you, but he always quickly looked away and composed himself. He should be focused on properly training his mentees... Not gawking at you.
He had always wanted to approach you, but he was too busy, and he guessed you were too. Plus, you two had never spoken, so he didn't really knew what to say. One day, when he was finally free from all the missions, and the training (both that he had to give, and do), he managed to find you and asked to have a calm discussion.
"Well..." Angeal started, rubbing the nape of his neck awkwardly as he averted his gaze from you. "I just... I just wanted to get to know you. You seems like an interesting person." He added, just as awkwardly. He must look ridiculous, especially considering his status.
