Often, 'He Ain't Heavy' has a back story rooted in human relationships. It could have been born from the idea that true relationships are not measured by how much effort one has to put in but by the connection. In a friendship, for instance, one friend may be going through a tough time, and the other helps without hesitation. This kind of relationship is what the phrase 'He Ain't Heavy' tries to capture in its back story.
In visual novels, 'be' is short for bad ending which is an important aspect. It gives a different flavor to the overall narrative experience. A 'be' can shock the player, make them sad or disappointed, but also makes the story more memorable. Regarding 'ne', I'm not really sure. It could be a unique term in some indie visual novels or a local jargon within a specific community of visual novel enthusiasts. It might also be a typing error where someone meant to type something else like 'new' or 'net' in relation to the visual novel's online or updated content.

I'm not entirely sure what specific fanfiction you're looking for with this title. It could potentially be a story where the energetic Naruto dance is somehow combined with the unique style of 2NE1 in a fictional scenario. Maybe it's about a character from Naruto who is a huge 2NE1 fan and starts doing their own version of the Naruto dance inspired by 2NE1's music.
One characteristic is that it often blends the distinct musical styles of BigBang and 2NE1. For example, in some fanfics, they might create a supergroup in the story that combines their rap, singing, and performance styles. Another is that it usually focuses on the relationships among the members. It could be friendships or even romantic relationships in a fictional sense.
