Kuro remains alive throughout the Haikyuu manga. The plot doesn't take such a tragic turn for this character. Instead, it emphasizes the team's journey and their passion for volleyball.
Hajimete no Gal manga doesn't feature nudity. It's more about the characters' growth and experiences in a teenage setting without crossing into that territory.
Kimi ni Todoke's manga has a conclusive ending that isn't sudden or out of the blue. The narrative progresses smoothly towards its finale, leaving no major loose ends and providing closure for the readers.
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.
