Right, if you have to choose the five boys to be your...
1 - Older brother
2 - Best friend
3 - Boyfriend
4 - Husband
5 - Younger Brother

Who'd be who? And why?

I'll start.

Older Brother Sakurai Sho
- He's smart, n he has younger siblings. I'm sure he's good at taking care of people...

Best Friend Aiba Masaki
- He's funny, and he always very genki. Life's never boring with him around... and he seemed like a good listener, somehow... He'll definitely cheer you up when you're down.

Boyfriend Matsumoto Jun
- Pretty boy. He knows great places to dine in, and you can count on him to bring you to wonderful 'dating sites', hehehe....

Husband Ohno Satoshi
- Yeah la, I like Ohno, but that's not why I chose him in this place. He knows when to be serious and when to be dorky (heh), he treasures his family and respects his mom and sister (so he'll take care of his wife too). Though he seems stupid sometimes, but i sense that he's very steady.

Younger Brother Ninomiya Kazunari
- I'd definitely be proud of such a younger brother. Always carrying his game around, i guess i won't stop nagging him to go and eat/bathe/sleep etc. Hehehe... But certainly it'll be fun with him around, it's normal for younger brothers to play pranks on older sisters. Maybe i can play some pranks on him too. Muahaha...

What about you people?

ooooh this is hard!

older brother - probably sho kun as hes super smart and he cares so much for his true friends and family. i dunno i just see him as being the really protective "i'll kill any one that hurts you" type, yet being kind and supportive.

best friend -
i was gonna put aiba here, but it has to be oh chan instead. i would never be unhappy with a best friend like him i think we would get on so well!  damn, its a shame i'll never get to prove it.

boyfriend -
Aiba chan!! hes so genki all the time yet hes really caring. i want a boyfriend that will be like my best friend. i think he could do that 

husband - eh?! this ones too hard - they'd all make perfect husbands; i want my husband to be the same as my boyfriend. can i do that? i suppose if i had to choose it woould either be jun or aiba ......or maybe ohno

younger brother - nino alllllll the way. i'd play gameboy with him all the time

first off,i wouldnt want any one of them to be my brother because that would be incest..but that would be a different story..

this is harder than i thought..but here goes..

older brother-sho-kun!he would be the perfect older brother(although he probably already is)..

best friend-nino!it would be so much fun just hanging out with him..maybe a couple of pranks here and there..

boyfriend-jun..definitely boyfriend material..although i probably would be very insecure having a boyfriend whos prettier than me..hehe..

husband-ohno maybe..from what ive heard hes very family oriented and thats always a good thing..plus it isnt very hard to imagine yourself with someone like ohno is it?my sister will kill me if she sees this..

younger brother-aiba..i would love to take care of someone as loveable as aiba-chan..

1 - Older brother
it would be Sho.. keio-boi! he'll be my advicer.. i know he'll guide me always.. he thinks like a 30 yr old (according to the 4 ~ AAA DVD concert). Sho is clever. He thinks everything quickly.

2 - Best friend
i'll go for Jun he can keep secrets ne? i know i can trust him when it comes to stuff like that.His basic concept is to act different from others.. its been how many years since they became ARASHI and still He and Aiba are still very close to each other.

3 - Boyfriend
its Ohchan he's funny! adorable Ohchan! when im bored i know he'll be the one to cheer me up  Because he is more talkative in daily life.

4 - Husband
AIBA im not being bias here ?! nyhaha! oh well! why aiba? hhmm  we have lots in common... Aiba is like an rare rainbow if rainbows were few. He has this colorful aura that is always with him! Our genki boy! He got these tantalizing eyes that made me wonder that there must something with in him.

5 - Younger Brother
Yeah! Nino my lil bro! hehe.. he's a game freak! he is easy to be absorbed in something that he likes. Take one example, guitar, he cannot stop being crazy about it. guitar! i love playing guitar but im that subarashii like him

not me. for some reason, he's a cuter boyfriend

Gawd, this is a hard one. Lemme think..

1. Older brother - Ohno Satoshi
Besides from our age difference (he's 12 yrs older), I really imagine Ohno as my brother. I like his personality and I want to bug him like.. "Aniki, I want this!!!! If you don't buy it, I'll tell it to Okaasan!" I'm very strange ne!? 
2. Best friend - Aiba Masaki
My friends have the same personality as Aiba.. they're carefree and genki just like him. He's fun to be with and when I'm sad; I count him as the persons I can talk to and never say bad things.
3. Boyfriend - Matsumoto Jun
I don't know th real reason why I chose Jun to be here.... it just came to my mind instantaneously. Maybe it's becauseof his aura that I perceive on him. It's really hard to explain nevertheless, I'm sure he's a great boyfriend. 
4. Husband - Sakurai Sho
Yabai! What I was thinking here!?  Anyway, Sho and I have many similarities regarding on our personality. And I think he will be a great husband and father because of his family upbringing and he can be funny yet disciplined at the same time.
5. Younger Brother - Ninomiya Kazunari
Neener! I just want him to be my otouto. Well, he's actually my otouto if you have read about the Korea con (he's 11 yrs old accor. to the Korean audience). And I love to hang out and play with him with his game consoles. And I also see him the person that I can goof around and do pranks on him. 

Uwaa! I'm not making sense!

Older brother: Matsumoto
Why: because he seems like an over-bearing brother type...the kind of guy who will never like whom his sister dates. and the kind of guy who would spy on his sister when she's on a date. but he'd also be the guy to protect his sister or defend his sister in any situation.

Best friend: Sakurai
Why: because he just seems like that kind of a guy. the kind of guy that you can talk to and he'll listen. you could talk to him about anything...even sex. he'd be the shoulder for you to lean on when you're having relationship troubles. and he seems like the kind of guy who is everyone's friend. if you're in school, he'd seem like the best lab partner or a good person to have in your study group.

Boyfriend: Ninomiya
Why: because he's that mysterious bad-boy that all the girls love, and all the boys hate. going on dates with him would be interesting, yet fun because he'll just be charming and romantic at times you wouldn't expect....and he seems like the kind of guy who would remember the anniversary of your first date or first kiss. he seems like the kind of guy who would go to your house in the middle of the night, stand infront of your bedroom window and serenade you.

Husband: Aiba
Why: because he seems very family-oriented. he loves children (and cooking). he seems like the type who will work hard to make his family live comfortably. and he will try very hard to help his wife and share the chores. i just get the feeling that he'd be a very eccentric husband/parent...kind of like the dad from the American Pie movie or something like that...but with lots of strange pets.

Younger Brother: Ohno
Why: he just seems like a younger brother type....quite childish and child-like. he seems like he'd be the perfect "baby-of-the-family" type....and he's already a "mama's boy". he seems like the kind of brother who goes snooping around his sister's room to read her dairy.

I MUST DO THIS.

Older brother - Nino. I know that sounds really weird, but I have only older brothers and for some reason, I feel Nino would fill that role perfectly. I think he'd be the kind of older brother who would play a lot of jokes on me, and be a jerk too, but at the same time, I think he'd be nice when he had to be. I don't need an older brother to really take care of me, I need an older brother who will make me laugh. He probably wouldn't let me confide in him, but I don't share information like that with my older brothers anyway.

Best friend - Aiba. It's tough because boyfriends can also be best friends, but I'd rather just have Aiba to hug without worrying about us breaking up and making things awkward. He's really really similar to me, he'd probably want to dress like a gorilla and walk downtown with me. And besides, I don't want to date someone like me. I'd drive myself up the wall. I like having *friends* who are similar to me, so I don't feel totally stupid. I think I could tell him anything and because Aiba's so sweet, he'd try to help me out... or at least try to make me feel better. And I'd like to watch his "experiments" so I could say, "This is such a bad idea..." but then try them myself. Yes, yes, we'd be really good friends.

Boyfriend - Ohno, for sure. We could do the whole date thing where we stay in and draw. How awesome would THAT be? It wouldn't have to be a very physical relationship. He seems like the kind of boyfriend who would go on a walk with me and would just be nice generally. And for someone as timid as me, I think someone as laid-back and (forgive me!) completely clueless as Ohno, we'd do just fine. :3

Husband - Sho. He's so mature and caring, I would feel that when I feel grown up enough for marriage, I want someone who's also grown up. And he loves kids, as do I, so that's a HUGE bonus. <3 And my parents would probably like him. And he has a fun side, which is definitely what a marriage requires, for sure!

Younger Brother - Jun. We could dish together, go shopping, and we could really talk and mess around. I've never had a younger sibling, I'm the youngest, so having Jun as a younger brother is ideal because he doesn't seem like he'd be too annoying. He'd be the chill younger sibling. He could be my over-critical younger sibling. Also, I didn't know where else he would fit... hahaha.

Older brother - Sho!! He's like the best big bro ever (if i'll tell you the reason why, it won't fit one post hehehe)
Best friend- Aiba. A funny and curious best friend would be nice.
Boyfriend- Ohno!! i love him sooo muchhhh. He's so cute and he's reliable and he'll make you laugh because he's such a dork sometimes. He'll sing his girlfriend some romantic songs or maybe paint her a picture.
Husband- ehh? should the husband be different from the boyfriend, that's kinda weird. Ohno would make a wonderful husband too.
Younger Brother- of course Nino!! We're both game addicts and we can maybe pull some pranks on our big bro, Sho 

as for Jun.... i dunno where to put him he can also be a best friend, i guess (this proves that i don't have Jun Bait Syndrome )
