Perhaps it could be a story of friendship and sacrifice. Tenten finds an orphan baby during a mission. Naruto, being the hero who always wants to protect the weak, offers to help her. They decide to raise the baby together in a platonic way. Naruto uses his experience of growing up alone to make sure the baby feels loved, while Tenten uses her skills to provide for the baby's physical needs like food and shelter.
For Naruto and Hinata, their relationship could develop in a unique way if Hinata starts teaching Naruto some of the more refined aspects of the Hyuga clan's techniques. This would create a new level of closeness as Naruto respects Hinata's skills. And with Tenten, she could be the one who arranges little 'get - togethers' for the three of them, which slowly builds a stronger bond between all of them.
Their relationship could be developed through a series of duels and challenges. At first, they see each other as opponents, but as they face off more, they start to understand each other's fighting styles and strategies. This could lead to a grudging respect. They might then start to train together in a way, not to become friends right away, but to better themselves as wizards, with Bellatrix learning some of James's more sportsman - like dueling ethics and James learning about Bellatrix's tenacity in battle.
The baby could inherit Naruto's chakra reserves and his ability to use the Rasengan. Since Naruto has an enormous amount of chakra, it would make sense for the baby to also have a large chakra pool. The Rasengan is one of Naruto's signature moves, and it could be passed down genetically or through training that Naruto would give the baby as it grows up.
One way could be through a time - travel or alternate - reality plot. Maybe Hermione discovers a way to go back in time and change Severus' fate. She sees his potential for good and they form a deep friendship that gradually develops into a relationship where they consider having a child together. This would focus on their mutual understanding and respect for each other's intelligence and abilities.
They could develop a relationship based on mutual admiration for their combat skills. Jacob could teach Edward some of his wolf - pack fighting techniques, and Edward could share his knowledge of vampire strategies. This way, they build a relationship centered around learning from each other.
Perhaps Tonks' crush could be redirected towards her own self - growth. She realizes that her so - called crush on Harry is actually a sign that she needs to focus more on her own life and relationships. So she starts to work on her own identity and how she presents herself in the wizarding world. This way, the 'crush' is just a catalyst for her personal development rather than leading to a romantic relationship with Harry.
They could develop a mentor - mentee relationship. Yato, being more of a free - spirited and somewhat reckless god, could learn from Bishamon's more structured and disciplined approach to her duties. Bishamon could teach Yato about the importance of honor and loyalty in the spirit world, which would help Yato grow as a god.
A way to develop their relationship could be through a series of comical misunderstandings. Say Naruto accidentally breaks one of Tenten's precious weapons. At first, Tenten is furious, but as Naruto tries to make it up to her in his own clumsy way, they start to see different sides of each other and become closer friends.
Well, they could be portrayed as friends. Maybe they are partners in some sort of adventure. For example, they could be on a quest to find a lost magical artifact. They work together, relying on each other's strengths. Scorpios might be good at navigating through dangerous terrains, while Rose could be excellent at deciphering ancient clues.
Their relationship can be developed through a mutual respect for their ninja skills. For example, they could train together and learn from each other's techniques. Neji could teach Hinata how to better use her Byakugan in combat, and Hinata could show Neji how to be more empathetic towards others in battle situations.
