The ring could be a magical or enchanted item. In the fanfic, it might have powers that start to affect Seulgi in strange ways. Irene then has to help Seulgi deal with the effects of the ring while also trying to maintain their relationship. This could involve going on a quest to find out how to remove the ring's power or learning to control it together.
Her grandmother might have given her the ring. It could be a precious family item passed down through generations. This would add a layer of family history and tradition to the story, and Irene would need to understand the significance of this heirloom in Seulgi's life.
I haven't actually read this fanfic, so it's hard to say exactly what's special about it. But generally, a good Red Velvet fanfic might have interesting characterizations of the members. It could be that in this fanfic, the plot revolves around a unique situation with the ring, perhaps it's a symbol of a special relationship or a mystery to be solved.
One possible plotline could be that the boy in the war is a hidden shinobi from a small village. He might have unique abilities that are crucial for the outcome of the war. For example, he could possess a rare bloodline limit that the enemy is trying to either control or eliminate. And Naruto, being the protagonist, might cross paths with him and try to protect him from the horrors of war while also learning something from his experiences.
One possible plotline could be that Naruto somehow gets bonded with the She - Venom symbiote. This gives him new powers and he has to learn to control them while still being true to his ninja ways.
In one plotline, Fleur could be the target of a curse that slowly drains her magic. Harry, as her bodyguard, has to find a way to break the curse while keeping her safe from those who might want to take advantage of her weakened state. This could involve seeking out ancient spells and potions, and they might have to journey to dangerous and mysterious places. As they do so, their relationship could evolve from Harry simply being a protector to someone Fleur deeply trusts and relies on, and there could be hints of a romantic connection developing between them.
One possible plotline could be about the new generations of avatars exploring uncharted regions of Pandora. They might discover new species and form unique bonds with them.
One possible plotline could be the public's reaction to the divorce. The media frenzy, public opinion polls swinging, and how it affects the political climate. Another could be the division of assets, especially if there are state - related properties or funds involved in some way. And perhaps the role of political parties in either trying to cover it up or use it to their advantage.
A plotline could revolve around Marceline preparing for the arrival of her baby. This might include her building a safe place for the baby, considering how her world as a vampire and adventurer might affect the child's upbringing. It could also show her seeking advice from her friends, like Finn or Jake, who might be both excited and worried about the situation.
Maybe Harry leaves the wizarding world and uses his magical skills in the muggle world as a mercenary. He could be hired for dangerous jobs that require a touch of magic but need to be kept secret from the muggles.
A possible plotline might be that a dark wizard is after Hermione because of her new - discovered connection to the Malfoys. Draco, feeling a sense of family loyalty despite their differences, decides to protect her. Along the way, they learn more about their family's past and the reasons behind Hermione being separated from them. It could also involve Hermione trying to reconcile her Gryffindor values with the Slytherin - like values of the Malfoy family. There might be a scene where they have to face their parents together, and the Malfoy parents have to accept Hermione as their daughter, which would be a huge shift in their pure - blood ideology.
