Sodapop Patrick Curtis , nicknamed "Pepsi-Cola," by his deceased father, is the middle Curtis boy. He's said to be "movie star handsome," and has silky, dark gold hair (real tuff) that he combs back with dark brown (recklessly, dancing) eyes and a goofy grin that you can't help but love (which is noted by Ponyboy after getting jumped by the Socials).
He is a high school dropout at 16½, and works at the local DX (gas) station with his best buddy, Steve, fixing cars and working the cash mostly. It's also mentioned that "he attracts (girls) like flies to honey," it is also said that girls, both soc and greasers will get gas there just to stare and flirt with him.
Sodapop is dating, and in love with Sandy near the beginning of the book, a pretty (greaser) girl with china blue eyes and blonde hair, before Ponyboy and Johnny turn away to the church in Windrixville, but when they return, Pony is surprised to find out that they broke up. It turned out that she was moving to Florida because her parents didn't approve of the idea of Soda marrying her. She clearly didn't love him back, and he was heartbroken.
