Why wasn't Yoona from SNSD in some of episode on Hello Baby?

Q. i forgot which episode she wasnt on but she came back episode 15.

A. She has other schedules, so she was busy doing other things/activities such as acting.

Did Yoona and Jessica from SNSD ever describe what kind of guys they like?
Q. I heard Jessica likes guys that are jerks to her?

what about Yoona? รข¥

A. I remember Yoona saying that the Japanese celebrity Kimura Takuya (I'm not sure if that's the right spelling) is her ideal guy. Jessica's ideal guy was Daniel Henney and Jung Woo Sung. It seems like Jessica likes really tall and manly looking guys.

I can't choose who to marry: Jessica or YoonA from SNSD?
Q. Please don't say both, that's just disgusting, a disgustingly sexy fantasy.

A. Lol! I'd say YoonA BUT there is a low chance you'll ever even marry her. LOL!
(Not trying to be mean) because she is in the Kpop industry and it'll be hard
for her to meet you and "date". She probably likes her own privacy for now, till
she likes someone then she'll make a move but for now I just think you guys
need to stop saying really false predictions that won't actually happen.
I think YoonA (Also including SNSD and all the other Kpop bands) need to have
their personal privacy and YoonA will pick who she wants and likes.
Sorry if I am offending anyone or being mean but it is true.

How to be like Im Yoona from SNSD ( Girls' Generation)?
Q. I wanna be like her because my boyfriend love her a lot, and i wanna be more pretty than her

I really want to be that pretty, but i'm ugly :/ so idk how to be that pretty :3 can you help me please *-* with some tips of her make up and stuffs ?

A. Haha this was a funny video...Asians are....a bit strange let's say :D

I don't think she's THAT pretty.

But if we're talking about makeup now, let me tell you what I think

1. BB cream or a good natural looking foundation to even out your skin tone
2. Black circle lenses
3. Curl lashes + black mascara
4. Thin line of liquid eyeliner on top lash line
5. Light pinky blush
7. Sheer pink tinted lip balm

A very natural look. And what it seems like it looks like she had a nose bridge implant or something...that's quite a bridge on an Asian nose.

Not only this, she just acts like she's cute. Just act like that I guess if you want to please your boyfriend.
