Yeah, Jessica may look cold, and she seems to be a bit of a perfectionist at work (fixing how other girls hold their mics, and stuff). But that's how you're supposed to act at work, right?
And like tama said, she really is a big softie. She seems to cry easily and stuff
She really gets attached to other people.
Whatever you do, don't believe anything they write on youtube comments. Those people are so hatefully biased that it's ridiculous! lol
& Jessica's singing is my favourite in SNSD. Even if I can tell that Taeyeon's a stronger singer, I like Jessica's tone of voice the best, and always look forward to hearing her. I think I have a thing for nasal-sounding voices (even if I don't ALWAYS like them)...
