Another fanfic to check out is 'Marin's Melody for Link'. In this one, Marin's musical talent is at the center. She uses her music to heal Link from a strange affliction. It's a shorter fanfic but very sweet, showing the power of their connection through Marin's music and Link's unwavering trust in her.
Marin does confess to Gojo in the manga. It happens during a crucial moment when their relationship reaches a turning point. The confession is filled with honesty and vulnerability.
There could be. You can search on fanfiction platforms and look for ones that are tagged as 'family - friendly' or 'general audience'. These types of stories usually avoid adult themes and instead focus on things like the emotional journey of Hanna Marin during her pregnancy, her relationships with others, and how she plans for the future with the baby in a clean and positive way.
Nope, Marin and Gojo don't end up as a couple in the manga. The manga follows a different narrative path for their relationship, concentrating more on other aspects of the story and character growth.
