There are many reasons. Music can be a great form of self - expression. For a girl, playing an instrument like the guitar or piano allows her to convey her emotions in a unique way.
Hachiman Hikigaya is a main character. He is a cynical and introverted high school student with a rather pessimistic view of the world and human relationships.
In Mortal Instruments fanfiction, you can read about characters like Clary Fray. She is a central character, a strong - willed girl who discovers she has Shadowhunter blood. Jace Wayland is another important one, a skilled and somewhat brooding Shadowhunter. There's also Simon Lewis, Clary's best friend who gets dragged into the Shadowhunter world and has his own interesting journey as he becomes a vampire in the series. These are just some of the main characters often explored in fanfiction.
Yukino Yukinoshita is also a main character. She is a beautiful and intelligent girl but has her own set of problems and insecurities. And there is also Yui Yuigahama, who is more of an outgoing and friendly character, often acting as a bridge between Hachiman and Yukino.
Hachiman is definitely one of the most interesting characters. His cynical and self - deprecating nature makes him stand out. He has this unique view of the world that sets him apart from the other characters. Yukino is also interesting. She is intelligent and reserved but has her own insecurities hidden beneath her cold exterior.
Hachiman is a key character. He is a cynical and introverted boy who has a unique way of looking at the world. Yukino is also important. She is a smart and reserved girl. And Yui, who is a cheerful and friendly girl, is another key character.
I'm not entirely sure as I haven't read it yet, but if it's in line with the previous 'oregairu' works, it might feature Hachiman Hikigaya as one of the main characters.
