Fans of the genre that the Alvin story belongs to would probably be the main audience. If it's a part of a particular series like a cartoon or a book series, then the fans of that series who like to see different interpretations of the characters, especially the more emotional ones like Alvin crying, would be the main target. Also, those who are into character - driven stories that focus on emotions might also be interested.
I'm not sure specifically what a particular 'alvin crying fanfic' is about as it could vary greatly. It might be a fan - created story centered around a character named Alvin who is crying. It could involve his emotional distress due to various plot - related events such as a conflict with friends, a difficult situation in his family, or a personal struggle he's facing.
Well, clearly Alvin and Theodore are the main characters. Alvin is often the more outgoing and sometimes mischievous one. Theodore, on the other hand, is usually the more gentle and kind - hearted of the two.
There could be a vampire hunter who is after Alvin. This hunter might be an old acquaintance who now sees Alvin as a threat.
The main characters are Alvin, Simon, and Theodore, the Chipmunks, and Brittany, Jeanette, and Eleanor, the Chipettes.
The main villain could be a big - city developer who wants to destroy the Chipmunks' forest home where the OC also lives. He is greedy for land and doesn't care about the animals or the environment. The OC and the Chipmunks have to come up with a plan to stop him, like getting the local community to protest against his plans.
Theodore could also be the main character. He's the kind - hearted and a bit more timid one. If he were the main character in a werewolf fanfic, it could be about how he overcomes his fear of the werewolf. Maybe he has a special connection with the werewolf, like he realizes that the werewolf is not all bad and tries to befriend it, which would be a very different take compared to the others.
There could be the elder weremunk. This character would be very wise and have a lot of knowledge about the history and traditions of the weremunks. He could guide Alvin on his journey to becoming a weremunk. Another possible character is the rival weremunk. This one might not like Alvin joining their group and tries to cause trouble for him.
I'm not sure who Alvin Zhou specifically is in this context. He could be a real person who has some connection to BuzzFeed Tasty, or perhaps he's a fictional character created specifically for this fanfic.
I assume Imelda is one of the main characters since she is in the title. And perhaps there is a character who is crying for mama Imelda, which could be her child or someone who sees her as a mother figure.
Obviously, Sakura would be one of the main characters. There could also be her best friend, who tries to comfort her while she is crying. Maybe a mysterious stranger who witnesses her crying under the sakura trees and is intrigued by her sadness.
