I don't have enough context to determine exactly who 'garp' is. It could be a newly created character by the fanfic writer, or it might be a character from a relatively unknown story that is being incorporated into the 'ace fanfic'.
Once upon a time, in a schoolyard, there was a girl named Lily and a boy named Tom. Tom had been teasing Lily for days about her new haircut. One day, Lily had enough. She walked right up to Tom, pushed him hard, and then started punching him on the arm. Tom was so shocked that he didn't even fight back at first. Lily yelled at him, 'Don't you ever make fun of me again!' and then walked away with her head held high.
Not really. In most societies, men are generally perceived as physically stronger, so it goes against the common expectation. However, when it comes to self - defense or extreme emotional situations like the ones I mentioned before, they do happen.
I'm not sure about its popularity. It could be popular among die - hard Glee fans who are interested in exploring different storylines and character interactions. But without specific data on views or readership, it's hard to say for sure.
One story could be in a self - defense situation. For example, a man was harassing a woman on the street, trying to grab her purse and touch her inappropriately. The woman, who had some martial arts training, fought back and beat up the man to protect herself.
In a neighborhood, a girl, Emma, noticed a guy, Ryan, being mean to an old lady. Emma was into martial arts. She stepped in between Ryan and the old lady. Ryan tried to shove Emma aside, but she blocked his move and delivered a series of punches and kicks. Ryan ended up on the ground. Emma's actions made her a hero in the neighborhood and taught Ryan not to be so unkind.
