X's Treasure (4X fanfic)

Despite both being raised in completely different ways, one being raised to be as polite and always use their manners whilst the other raised to be much more confident and outgoing. It seems that Four may actually be what X was searching for after all, there just seems to be something about the integer that makes them extremely curious to find out more.

So basically in this fanfic (or maybe even AU?) X was raised to not raise their voice at anyone, to not lead anyone, to not use their abilities in front of anyone, to not be seen as weird or stand out to anyone meanwhile Four was raised to be bold, to take charge, be more expressive and even show off their abilities. However X is slowly starting to get sick and tired of living that boring lifestyle so when he first meets Four on that special day he had found out that he had really missed out on so many opportunities.
