f(x) Krystal Likes To Hide Her Face 

1:37 omg she looks exactly like sica

krystal shouldn't hide her smile, her smile very pretty.

if many people said that yoona is the most beautiful in kpop industry, So krystal is the 2nd most beautiful in kpop industry because many people said that krystal and yoona are look a like even taeyeon agree with that.

she looks best with a simple messy ponytail in a hoodie. looks comfortable for her!

She is so cute and pretty

I like her smile her smile so pretty ;)

Krystal looks so fucking cute with that red flower

Yoona covers her mouth when she laughs sometimes but yeah Krystal is to pretty to be hiding her face, I used to do it and it became a hhabit

krystal used to be so much happier in the old times...now I can't see her like this anymore. I hope kai bring her so much happiness

She is toooo shy to open up often....yet,verrry pretty !! Im krystalised! ☺️

1:09 :O :O :O YoonA Ah~~~~~~~~~~~~~~

She looks so much like Yoona from SNSD xD

Jung sisters are really visuals,,i even thought she's the younger sister of yoona but it turned out she's sica's sister ☺️

@3:19 She has one of the gorgeous smile in the world..

why do you need to hide that pretty face

she's just being modest ^^

She is beauty than jessica her sister and butter

I wonder is she wakes up and realizes, "Oh hey, I'm f(x) Krystal."

I'm like krystal. I think its my mannerism. Or because I'm too concious about myself. I always cover my face with my handkerchief or my hair or hands.

I JUST WANNA HUG HER UGH

"Beauty lies in the eyes of its beholder" -a wise dude

Lmao chobits XD baby jung is too cute when shez shy lol

me too because of watching krystal all the time it's became my habbit and sometimes i love sulli open laugh wooow cute

1:09 yoona is that you? ^_^''

Krystal hides her face because she doesn't like the way she looks when she laughs. I think she looks absolutely perfect when she laughs hard.

Krystal and Jessica are both beautiful, I wonder what their parents look like?

her smile is gorgeous

omygosh my childhood lol chobits

Love her smileeeee

You know I really love Amber, but Krystal is so cute Amber AND Krystal hide their faces when they smile or laff. Why??? So pretty both of them, but Amber has that "it" factor for me!!!

Krystal's eyebrows when she scowled at 1:39 make her looks like Jessica

Krystal ! In my Opinion why krystal hide her face it's because she is so very shy. don't be so shy unnie. Guys Who 's that guy ? that have appeared in this video ??

what if she thinks she's imperfect? thats why she's hiding her face and all thats just stupid and ridiculous i dont even think she has flaws lol she's so damn perfect
