I'm not sure exactly what the 'Trouble in Paradise' full story is about without more context. It could be about a relationship that has hit a rough patch in a seemingly idyllic situation. Maybe it involves two lovers who had a great start but now face issues like communication breakdown or external pressures.
The main plot often involves some sort of conflict or complication in an idyllic or seemingly perfect situation, which is like a 'paradise'. However, without actually reading the specific 'Trouble in Paradise' novel, it's hard to be more detailed.
In Hunger Games fanfiction, 'Trouble in Paradise' could refer to a relationship falling apart. For example, if two tributes who had a budding romance in the arena face difficulties outside of it. Maybe one of them has to deal with the trauma of the Games differently from the other, causing a rift between them.
One way is through character relationships. For instance, if a character who was once popular and had a great life in the Capitol suddenly falls from grace. Their friends turn on them, and this could be seen as 'Trouble in Paradise' as their once - idyllic social situation is ruined.
FF7 Rebirth doesn't complete the story. It usually leaves room for continuation and builds anticipation for the next installment. The plot might have loose ends or new storylines introduced to keep the franchise going.
FF7 Rebirth has a story that can keep you engaged for a good while. The main storyline alone offers many hours of gameplay, not to mention the optional content that can further extend your experience.
Perhaps it's a story about a family living in a beautiful place. They had everything they needed and were very happy. But then something unexpected happened, like a health issue in the family or a feud between family members. This led to 'trouble in paradise'. The full story would include all the emotions, the events that led to the situation, and how the family is coping with it.
Well, in FF7 Rebirth, there is indeed free roam after the story. This is a great feature as it gives you the chance to fully immerse yourself in the world. You can go back to different locations, interact with characters you might not have had enough time with during the main plot, and maybe even find some hidden quests or items. It really adds to the replayability of the game.
