Just mentioned your name, should I be afraid ?
Wondering why I'm response in such this way ?
Because of your icy look ! *Scared*
Honestly, your appearance, is REAL as everyone said, arrogant. Actually, I'm kinda scared to see you . . . But, in Oh ! MV, not Taeyeon or Tiffany attracts me, it's you !
I found, that you're active and cute in this MV
Then, SNSD had released Run Devil Run as 2nd comeback after Oh ! You looks gorgeous at HERE ! 
I thought, you're gorgeous, but . . .
You're cute !
Stunning ! Your vocal is angelic !
As I watched variety shows, I'd found out your warm heart ! You're not cold as everyone said
> _ < Do you know, now you're the cutest member among SNSD in my heart ?
You're one of the fashionista among SNSD

Girls' Generation Ice Princess Jessica !
You're the unique member among your 8 sisters. I do admit, you're not attractive to me, at 1st sight. But, when I watched you on Genie, I start to look at you, vocals and dancing skills. *Hmm, not bad * Not a long time, you'd give me a surprise with Oh ! You look pretty with that hairstyle and the choreography's outfit ! ^_^ OK, you're giving me a "SHOCK" with Run Devil Run. During that time, my eyes are only spazzing on SNSD 3 main vocalists : Taeyeon, Tiffany and you. I'm really love your hairstyles and outfit at the MV ! Your icy look As I watching you more, I didn't realize that myself almost being "electrified" ! @_@ By the way, stay fresh by being silly ! ^_-
Jessica, Ice Princess, when you show your emotions its heart breaking for me
You're so beautiful, talented, lovely, amazing and glamorous
SARANGHAEYO!
ice princess *-*
I LOVE YOU!
