When Emelia heard this she was surprised, at first she thought she had miss heard what he said and stared at his face, but then after a while, she realized she didn't mishear anything, whatever she had heard was correct Bernard was really asking out on a date, as she thought to this point her face immediately became flushed red, after the incident with him biting her on the neck.
Emelia realized that she was gradually growing feelings for him, although she had no clue if it was because he was the first person who offer to be her friend during the time when everyone got to the academy newly or because of the bite, or because of something else entirely but she knew she was gradually falling for him.
