If Girls’ Generation was your unnie/noona (older sister)…
TaeYeon will bully you and crave for omma and appa’s attention. She will not be sweet and she will be rough. If you’re a boy and you like car toys, you’ll get along very well during play time. If you’re a girl who also likes these kind of toys than dolls, then she’ll get along with you even better
Jessica will really love you and baby you. She’ll be almost like your second mother. She’ll introduce you to her friends. You’ll be that little dongsaeng everybody knew to be so adorable and funny because of the embarrassing things your sister says about you.
Sunny will be a sweet, caring sister who you’ll look up to. She will do cool things that always catch your interest, and you’ll crave to be her best friend.
Tiffany will love anything pink as we all know. She will not stop talking and will force you to probably play tea parties with her. If not tea parties, she will make you watch her favorite Disney movies for as many as about 50 times. But other than that, she will take are of you well. She might be a bit bossy, though…
HyoYeon will be another bully. She will play pranks on you and you’ll end up crying at every end of the day if you’re not used to it. And since she’s older than you, you can’t exactly fight back even though you want to. But atleast you’ll get a good laugh everyday because of her witty jokes.
Yuri will be a fun Unnie to play with as long as its not a competition game. If it’s a competition game, she will be too competitive and annoying to deal with. She will also play some pranks on you like putting bugs under your pillow if you hate them. Her pranks will never be too harmful as HyoYeon’s though…
SooYoung will be that Unnie who finishes whatever you have left in your plate. And if she doesn’t get a fair share because of you, she will hold a grudge for the next few hours.
Yoona will also be that Unnie who plays pranks. If your relationship with her is close enough, she will drag you into her devious plans to ruin the cake of your other sibling’s birthday cake for fun.

Sharing a room as teenagers
TaeYeon will turn to byuntaeng mode when you change clothes. If you’re not careful enough, she might just pass by and smirk at you without you noticing. If you’re body is really hot, there’s a high possibility that she will say a really inappropriate joke, one that you could either laugh at or make you cringe.
Jessica will also will be a byuntae when you change clothes, but much worse than TaeYeon. She will casually take peeks, and if lucky, snap pictures of you undressing if she finds your body endearing. Be very careful of iPhone camera click sounds. Those will be her treasures forever so don’t get on her bad side if you don’t want her using those photos as blackmail.
Sunny will be the source of mess in the room, unless you yourself are a mess, too. She will grab your butt or pinch your elbows at such a random time you will beg your parents to give you a room of your own.
Tiffany will puke pink and girly things all over the room. You cannot make her changer her mind.

Yuri will tell you to clean the room if you have a small piece of mess around. She will not tolerate your mess and will get angry at you if you don’t act fast.
SooYoung will lock you out when she needs to (whether it’s for byuntae purposes or not). If she forbids you to enter, you can’t do anything about it because she’s the Unnie.
Yoona will also invade your privacy whether you like it or not. But as to the choices of who gets to decorate the room, she will be fair and make sure you have enough of your identity and her identity in it.
SeoHyun will have a shelf full of books… but she will also have a shelf full of random toys, stuffed toys, and figures she fangirls over. There will be Keroro merchandise, Jack Sparrow merchandise, and just about anything she found cute over the television. And also, she will not tolerate your messiness like Yuri.
As for nighttime, lights will be closed at either 8 pm to 11 pm. She will not stay up at midnight.
