No. Reading manga is just a hobby. It doesn't mean you're a weeb. A weeb is typically characterized by an excessive and sometimes inappropriate infatuation with all aspects of Japanese culture, beyond just reading manga.
Definitely not. Wednesday is a made-up tale. It takes us into a fictional world filled with magic and intrigue. It's all for the purpose of giving us an engaging and enjoyable viewing or reading experience.
It's a blend. Big Wednesday incorporates elements of truth along with creative imagination. The story might draw from real events or people, but it's not a straightforward documentary-style account of actual happenings.
In some ways, it is. The characters and their experiences in Wednesday Wars have elements of authenticity that make it seem realistic. However, there might also be some fictionalized aspects for dramatic effect.
