Hey, this was kind of nice. It focus on a very minor aspect i.e a cosmetic aspect i.e Winry's earrings and Riza's hair. It's cool to see how they influenced each other. By the way, does every OVA have to end on a dismal note or something??
It's funny to find out that the reason why Winry has so many earrings on was because of the Elric Brothers bribing her with a lot of them so they won't have tools thrown at their heads when they repeatedly come in for repairs.
It's cute that Winry had her ears pierce to look like Hawkeye while Hawkeye grew out her hair to look like Winry.
