In some fanfictions, Hermione might be comforted by Sirius after an encounter with a dark wizard or a particularly difficult spellcasting session. Sirius, being a skilled wizard himself, would reassure her. He might take her on a walk around the grounds of Grimmauld Place, showing her the beauty in the old, dark place and telling her that just as the place has hidden charm, so does she, even in her moments of self - doubt.
Imagine a situation in fanfiction where there is a powerful magical artifact that is attracting unwanted attention. Hermione, being one of the few who can understand its significance and power, is in danger. Sirius Black, who has a sense of loyalty to those he cares about, would become her bodyguard of sorts. He would stay by her side, use his magic to create protective barriers, and fend off any who try to harm Hermione or take the artifact from her. He might also teach her some defensive magic techniques that are not taught in the regular Hogwarts curriculum to better equip her for such dangerous situations.
At first, their relationship might start out as a simple acquaintance - type thing. Sirius sees Hermione as a smart young witch, but as he comforts her more, they start to develop a deeper bond. Maybe they start sharing secrets about their past traumas.
One good fanfiction could be 'The Unlikely Bond'. In this story, Hermione and Sirius Black form a strong friendship as they work together to solve a mystery within Hogwarts. They exchange knowledge and wisdom, with Hermione sharing her academic insights and Sirius providing his practical experience from his years as a Marauder.
One common plotline is Sirius being protective of Hermione. He might see her intelligence and bravery and feel drawn to her. He could protect her from various threats in the wizarding world, like Death Eaters or other dark forces.
One key element is their mutual admiration. Sirius sees Hermione's intelligence and courage, much like he saw in James. Hermione, on the other hand, respects Sirius for his loyalty and his fight against the dark side. Another element is the generational gap. They come from different times in the wizarding world, but this actually enriches their bond as they learn from each other.
In a more dangerous situation, like after a particularly scary encounter with a dark wizard. Remus would be there to comfort Hermione. He'd hold her trembling hands and assure her that she's safe now. He'd remind her of all the times she's been brave and how she's a crucial part of their fight against the dark forces.
One popular theme is mentorship. Sirius, with his experience in the wizarding world, can mentor Hermione. Another theme is mystery - solving. They could work together to solve a mystery in Hogwarts, like the origin of a strange magical artifact. Friendship is also a big theme, showing how their different personalities can complement each other.
One possible scenario could be that Sirius Black spanks Harry as a form of discipline for some dangerous or disobedient behavior that Harry has engaged in within the context of the fanfiction's plot.
In some fanfictions, Hinata uses her Byakugan to help Naruto in his training. She carefully observes his movements and points out the flaws in his techniques. This act of selfless assistance is very heartwarming. Naruto, who has always been somewhat of a self - taught fighter, really appreciates Hinata's help. It also deepens their relationship as they spend more time together during the training sessions.
In these fanfictions, a really sweet scenario could be that baby Sasuke is sick. Itachi takes care of him day and night, making him soup and staying by his bedside. Sasuke, in his feverish state, mumbles about how much he loves his big brother. Itachi, touched, promises to always protect him. This shows the deep, caring relationship between them that fanfiction often explores.
