This book was called " A Concubine in Power: A Blessed Wife in the Garden." The female lead was Hua Jinyue, a medical doctor. She caused the villain, Xiao Ruyang, to be dissatisfied with her throwing embroidered balls.
The main differences are in their expressions and some minor details of personality. In the manga, Deku might seem a bit more intense, while in the anime, he's sometimes presented a bit softer.
I'm not sure specifically which 'woman throws table story' you are referring to. There could be many such incidents where a woman throws a table perhaps out of anger, frustration, or in a moment of extreme emotion. Maybe she was having an argument in a restaurant and lost her temper, or there could be some personal issue at home that led to such an outburst.
In 'deku meets future deku fanfiction', perhaps the future Deku warns the present one about upcoming threats. He could tell him about villains he'll face in the future and how to defeat them. This would give the present Deku an edge in his battles and also in his growth as a hero.
Well, obviously Deku in two forms - the younger and the older version are the main characters. The younger Deku is the one who is still growing and learning, while the older Deku has more experience.
As of now, Deku is very much alive in the manga. The plot hasn't reached a point where he meets such a fate. Usually, main characters like Deku have significant story arcs and aren't easily killed off.
It could be that Harry throws the tournament as a way to promote unity among the wizarding community. He might include challenges that require teamwork, like a group spell - casting competition where participants have to combine their magic to achieve a certain goal. And he could also invite wizards from other schools to participate, not just Hogwarts students.
Obviously, the students from Hogwarts would be the main participants. The Gryffindors, Hufflepuffs, Ravenclaws and Slytherins would all be eager to show their skills.
