Girls' Generation's Jessica is probably concerned that f(x) Krystal will choose a reckless guy, which I can understand. At my school, I see many girls go after guys based on looks and popularity. These guys also happen to be the ones who show the least commitment with their work and do bad things like smoke weed. Times are changing and nowadays guys aren't the only ones being superficial. I think Jessica is noticing this shift and trying to prevent Krystal getting hurt in the long run.
Girls' Generation's Jessica showed disapproval toward her younger sister Krystal's taste in men while the two were hanging out at a cafe in the second episode of their On Style reality program 'Jessica & Krystal' which aired on June 10.
In relation to Krystal's ideal type, Jessica said, "There isn't an exact one, but there's a feeling. She likes someone who gives off a slightly odd feeling." Krystal replied, "A feeling is important for every person. It is hard to give off that feeling."
The two revealed they often talked about men. Krystal, in particular, complained that her sister would always show disapproval towards men that Krystal liked.
Krystal revealed she liked men who were in the mold of Johnny Depp, saying, "When Johnny Depp and Kate Moss were dating in the past, I wanted to become a couple like that." Her sister said, "I am against a man like Johnny Depp. You probably know that. A person like that isn't great. You're in a bit of a rebellious phase, that's why. Why do you have so many problems with the world? You just need to meet a straight-edged person."
Krystal went on, "Our criteria for what is 'straight-edged' could be different." Refusing to lose, Jessica said, "There are certain people whom anyone could look at and judge, 'That person is not straight-edged.' I think you are often attracted to people like that."
Krystal wondered, "Is it because I'm young?" to which Jessica replied, showing her sisterly concern, "My goal is to change you a bit. I feel like you won't be happy at all later on."
Honestly, big sister needs to mind her own business. Krystal needs to find her own way through life and sort out what is and isn't right for her. As long as she isn't being verbally or mentally abused, then she should be free to explore different types of men. She will instinctively know what she's comfortable with unless she's a complete idiot.
