Disillusioned Reunion

Aries and Ross were best friends when they were kids. But when Ross had to move to another country, the two lost contact with each other ever since. They would reunite after 15 years, but things have changed drastically now that they are adults. Aries used to be an outgoing kid, but now he's a shy introvert. Ross used to be innocent and sweet, but now he's a playful flirt.
