One of the main features could be the character development of the sister. Starting as a gal - like character, she may grow and change throughout the story. There could be plotlines about her making friends, dealing with school bullies or social situations due to her appearance and style. And of course, the relationship with her brother or other family members would be a central part of the story, with their interactions evolving over time.
Another option is 'Oreimo'. It has a somewhat similar theme of exploring the relationship between siblings in a rather unique way. It delves into the life of the brother and sister duo, showing their daily interactions, misunderstandings, and the growth of their relationship over time.
Sorry, my answer may not be accurate. As a fan of web novels, I don't have the experience or ability to read novels or understand the genre of novels. But according to the information I know, gal usually refers to a type of video game in Japan where players play a role in the game to talk and interact with other players.
Although there are many excellent Japanese gals, they are usually not group dramas because they usually tell the story from the perspective of a single character. On the contrary, group dramas usually referred to telling a story from the perspective of multiple characters. These characters were connected to each other to form a whole.
Of course, this is just some information I know. If there are other questions, I will try my best to answer them.
