Wanna be a pretty girl [Osamu Miya]

Osamu and Atsumu were inseparable. They rarely left each other's sides and often entertained the idea of going everywhere and experiencing everything together. It was a promise that they swore never to break.

Throughout the years, not a single secret was hidden between them. Their every thought was shared, from complaining about their homework in the second grade to wondering if they would still be twins if they were dinosaurs. They were a strange duo, everyone always mused, but their tight bond was like no other.

So why was it that Atsumu was suddenly having difficulty speaking to his twin?

I didn't write it I just found it and thought "pity it is not on Wattpad yet" so I decided to paste it here <3
