What if Yoshino Nanjo and Riho Iida were born in 1980?

In reality, we know that Yoshino Nanjo and Riho Iida are both Japanese actresses, the first one was born in 1984, while the second one was born in 1991.

But in this alternate timeline, what if both of them were born in 1980, and not in two different cities?

Changes

 * Their birth date would've been May 10th, 1980.
 * Unlike reality though, they would've been born in only one city, Kyoto.
