I'm not sure if there is a specific existing fanfiction on this exact plot. However, if it were to be written, it could explore how Romeo and Indi's relationship would change with the news of pregnancy. Maybe they would face challenges from their families or friends at first, but then grow stronger together as they prepare for the new life.
The plot could revolve around the couple's struggle to balance their personal lives and the upcoming addition to their family. They might have to deal with financial issues, like how to afford a baby. Romeo could start working extra hours, and Indi might try to cut down on some of her own expenses.
One of the great indi games with an amazing story is 'Undertale'. It offers a unique take on the RPG genre where your choices really matter. You can choose to befriend or fight the various monsters you encounter, and the story unfolds differently depending on your actions. Another is 'Stardew Valley'. While it may seem like a simple farming simulator at first, it has a rich story about building a new life in a small town, with deep relationships to form and mysteries to uncover. Then there's 'Hollow Knight', which has a beautifully dark and mysterious story set in a bug - filled, decaying world that you gradually explore and piece together as you progress through the game.
In a way, it has elements of truth. It's fictionalized but might draw from some real-life situations related to bird conservation and human-bird interactions.
Yes, 'Fly Away Home' is inspired by real events. It takes elements from real-life stories of people's experiences with birds and their efforts to help them.
