In a fanfic, the character might recover on their own if they have a latent ability or hidden strength. They could tap into their inner reserves of power, kind of like an adrenaline rush but on a more supernatural level. It could also be that the shock of being knocked out by the Haoshoku Haki wave triggers a transformation or awakening within the character that helps them recover.
In a fanfic, if a clash of Haoshoku Haki wave knocked someone out, it could lead to a major shift in the power dynamics. For example, the side whose member was knocked out might be thrown into chaos, with their allies panicking or becoming enraged. It could also serve as a plot device to show the overwhelming strength of a particular character who unleashed the Haki wave.
In Naruto fanfiction with Haoshoku Haki, it could be incorporated in battles. For example, a powerful Naruto might unknowingly use a form of Haoshoku Haki during a crucial fight against a strong enemy. This could be shown as his intense willpower overwhelming his foes in a way similar to how it works in One Piece. It might cause some enemies to faint or lose their fighting spirit.
One aspect that makes it unique is Naruto's already existing strong will. In the original Naruto series, his willpower is a major factor in his growth and success. When combined with Haoshoku Haki in fanfiction, it amplifies this willpower in a different way. Instead of just inspiring his comrades, it can now be used as a weapon against his enemies.
The family can start by being honest with each other. The wife should take responsibility for her actions. The husband needs to express his feelings openly. They may also involve a family therapist who can guide them through the process of healing and rebuilding trust.
In a fanfic where Naruto uses haki, it could change his relationships with other characters too. For example, if he shows this new power, some characters might be in awe of him, while others might be jealous. His training to master haki could also lead to new interactions with mentors or allies who are familiar with this power. Also, his use of haki could potentially attract the attention of new enemies who are interested in this unique ability.
One way for a boy to recover is through professional therapy. A trained psychologist can help him work through his emotions and fears.

An OC's Haki can be developed through intense training. Just like how Luffy and the others train in the One Piece world. They could face difficult opponents and learn from each battle, gradually strengthening their Haki. For example, if they constantly fight against Logia - type devil fruit users, their Armament Haki would improve to counter their intangible forms.
In 'naruto haki fanfic', Haki can change the Naruto universe by adding a new layer of power. For example, it can make battles more complex as characters now have to consider both chakra and Haki.
