However, depending on how the fanfiction is written, he might eventually come to understand Merlin's reasons for secrecy.
The girl herself would likely be very embarrassed. She might turn red in the face and try to act like it didn't happen. Some classmates might giggle or laugh, especially the younger students. Others might be more understanding and not react at all, or they might even try to comfort the girl if they see how embarrassed she is.
