As I don't have much knowledge about this particular fanfiction, we can only speculate. If the 'neck' is a key element, it might be related to themes of vulnerability. A kiss on the neck can be seen as an intimate act, so perhaps themes of trust and intimacy are common. It could also be that the story is set in a world where such an action has special significance, like in a supernatural or fantasy setting. In that case, themes could include magic, power dynamics, and the consequences of such an intimate act within that fictional world.
