Anyone who is close to Lesly and has been privy to the events in the story could potentially tell it. It could be a friend who has been there through it all, or a family member who has some knowledge of what happened. However, they should respect Lesly's privacy if it's truly a secret story.
I'm not sure specifically what the 'lesly secret story' is as there could be many stories with that name. It might be a personal story about someone named Lesly, or it could be a fictional tale created within a specific group or community.
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.
