No, they aren't. There's no indication of them being in a romantic relationship in the manga.
As far as I know, Marin and Gojo aren't dating. The manga doesn't present any plotlines suggesting that. Maybe you got some wrong information or misunderstood certain scenes.
Character relationships are also a big theme. Not just romantic ones, but also friendships and rivalries. There are many fanfictions that focus on how Korra and her friends grow closer over time, or how her relationship with her enemies evolves from pure animosity to something more complex. This could involve characters like Asami and their friendship which was so important in the series. And then there are the rivalries, like between benders of different nations competing in friendly or not - so - friendly contests.
One shortcut is to use writing templates or formulas. For example, in many romance novels, there's a common pattern of boy - meets - girl, they face some challenges, and then they get together in the end. You can adapt this to your own story. Another effective way is to write short, punchy scenes. Don't waste time on long, drawn - out descriptions in the first draft. You can always add more details later. And if you get stuck, skip that part and come back to it later.
Another plot could be that they are trapped in an alternate timeline where they have to rely on each other completely to find their way back home. During this time, they learn about each other's past traumas and help each other heal.
One time my wife was trying to make a simple pasta dish. She accidentally put salt instead of sugar in the sauce. It was so salty that we couldn't eat it at all. Another time she burned the cookies because she got distracted by a phone call.
Bella often becomes a stronger character. She might start to focus more on herself and her own growth. For example, she could learn self - defense or focus more on her studies. As for Edward, he usually realizes his mistake in leaving Bella. He may go through a period of self - loathing and then try to find a way to come back to her. In some fanfictions, other characters like Jacob become more important in Bella's life during Edward's absence, and this changes the dynamics between all of them.
One common theme is the struggle against the odds. In Buffy and Walking Dead fanfic, the characters often face overwhelming challenges. For example, Buffy characters might be out of their element in a world full of zombies, and they have to use their wits and skills to overcome. Also, the theme of redemption can be seen. Some characters who have made mistakes in their own worlds get a chance to make up for it in the new combined setting.
Also, 'The Haunting of Hill House' by Shirley Jackson is a great horror novel. It tells the story of a group of people who stay in a supposedly haunted house. Jackson's writing style creates an atmosphere of unease and dread that slowly builds throughout the story.
In some neighborhoods, Hispanic guys have started initiatives to create safe spaces for everyone, regardless of gender or sexual orientation. They organize events and activities that bring people together, and through these interactions, they are able to change mindsets and build a more inclusive environment. This not only benefits the LGBTQ+ community but also enriches the whole Hispanic community as a whole.
Another possible theme could be the relationship between the knowers and the non - knowers in the short story. This could involve power dynamics, secrecy, or how knowledge is shared or withheld among different groups of characters.
I'm not sure specifically as it could be a very unique or even self - created concept. It might be a visual novel that features a character named Robin who is gay, perhaps exploring his life, relationships, and personal growth within the story.
