One possibility could be that Ed and Ling are characters in a fantasy world where their marriage is part of a political alliance. The ring could be a magical heirloom that has significance in their union, and the mention of 'pinky toe' could be some sort of strange or endearing cultural ritual in their fictional land. Maybe during the marriage ceremony, the pinky toe is marked with the ring in a unique way that symbolizes their bond.
In the fanfiction, the ring could be a symbol of a love that Ed and Ling have for each other that transcends normal boundaries. The pinky toe could be used as a metaphor for something small but important in their relationship. For example, it could represent a small gesture or habit that they share that is unique to their marriage. And the story could be about how their love grows and overcomes obstacles through this unique connection.
Perhaps the ring is cursed, and it has some strange connection to the pinky toe. In the fanfiction, Ed and Ling's marriage is threatened by this curse. The story could revolve around them trying to break the curse to save their marriage. The pinky toe might be the key to the curse, like it's the part of the body that the ring's magic latches onto in a negative way.
The ring might be a family heirloom that is passed down in Ed's family. In the context of his marriage to Ling, it holds great significance. The pinky toe could be involved in a ceremony where the ring is placed on it symbolically to show their union. It could be a very unique cultural or magical practice in the world of the fanfiction.
One idea could be that Ed and Ling discover a hidden power within the ring that has a connection to their marriage. For example, it could be a power that only activates when they are truly in love and committed to each other, and this power helps them face a great threat in their world. Another plot could be that the ring is a family heirloom that has a prophecy associated with it regarding their marriage, like they will bring peace to their two kingdoms if they stay married. A third idea is that the ring gets lost and in the process of finding it, they learn more about each other and their relationship deepens.
Ed could start as his usual headstrong self but through the experience of marriage, he becomes more patient and understanding. For example, when Ling has different cultural traditions regarding their marriage, Ed has to learn to respect and adapt. Ling, who might be seen as more reserved initially, could become more open and affectionate as the marriage progresses. This can be shown through small gestures like holding hands more often or sharing deeper thoughts. The challenges they face in relation to the ring can also shape their personalities. If the ring brings out insecurities, they can work on overcoming them and grow as individuals within the marriage.
Well, it could start with Ed being drunk and somehow his path crosses with Ling Yao's wife. Maybe he stumbles into a situation where he has to protect her from some danger due to his drunken state-induced bravado. And then, as they interact more, a strange bond forms between them, which is complicated by the fact that she is Ling Yao's wife.
Redemption is also a theme. Greed, being a homunculus, has his own set of issues. Fanfictions might explore how Ed could influence Greed Ling towards a path of redemption. And of course, adventure themes are common as both characters are from the world of Fullmetal Alchemist which is full of alchemy - related adventures.
One possible plot could be that Pinky has always been curious about the outside world of the Pac - Man maze. One day, a strange lemon - scented portal appears. Pinky, being the adventurous one, enters it and ends up in a different dimension. Pacman, noticing Pinky's disappearance, follows him. In this new world, they discover that the lemon - scented environment is slowly affecting their abilities. They must find a way to reverse this effect and also figure out how to get back to their own world while dealing with the unique challenges of this lemon - fanfiction world.
I'm not sure if there is specific 'drunk ed x ling yao wife fanfiction' available. Fanfiction can be quite niche and vary greatly in availability depending on the popularity of the characters and concepts within a particular fandom. You might try searching on specialized fanfiction websites, but there's no guarantee you'll find something with that exact pairing.
There are indeed some out there. These fanfictions usually delve into the chemistry between Homunculus Ed and Ling. They might rewrite parts of the original story to give their relationship more depth, like having them team up against common enemies in ways not shown in the official plot.
It could be a giant lemon - themed monster that wants to turn the Pac - Man world into a lemon - only place. This monster might be jealous of Pacman's popularity and sees the lemon - themed transformation as a way to make everything his own.
One possible plot could be that there is a magical event that causes Pacman and Pinky to swap abilities. Pacman now has Pinky's speed and stealth, and Pinky has Pacman's ability to eat dots. This leads to a lot of chaos and confusion at first, but eventually, they learn to use their new abilities together to solve a bigger problem in the game world, like a new enemy that neither of them could face alone.
