Oh-chan Drama confirmed Official Website Translation

Asahi TV Official site says:

歌のお兄さん　（Uta no Oniisann)
The Singing man/Singing brother - sort of a slang/nickname for male Kids TV presenter

人気絶頂！嵐の大野智がテレビ朝日系連ドラ初主演！
Very popular Ohno Satoshi from Arashi will star in the new TV Asahi drama series!

ふがいな～いオトコが突然“歌のお兄さん”に… 窮屈な世界で奮闘する痛快サクセスストーリー！
A no-hoper　finds himself cast as a kids TV presenter...It's a story of a guy who struggles his way to success in such an uncomfortable/strict/constrained world of entertainment.　

Comment from Ohno:

前回（の『魔王』）とはまったく違うコメディなので、どう演じようか楽しみです。
As this character is so different from the one I played in Maou previously, I am excited to think about how to act it.

自分の素にも似ている感じの役なので、楽しんでやれたらと思っていま す。
The character resembles myself a bit, so I hope to enjoy playing this role.

見ている方々にも楽しんで見て欲しいし、健太が頑張っている姿を見て、自分のやりたい仕事ができていない人たちを勇気づけられたらいいなと思います。

I would like the viewers to enjoy watching it, and it will be nice if the story of Kenta　(Ohno's character's name) putting his best effort can encourage/give hope to those people who are unfortunately not following their dream career.

　（歌のお兄さんの）衣装すごく派手で・・・、ジャニーズJr.に戻ったような気分です（笑）
The character's costume is really showy ...it makes me feel like I have gone back to my Johnny's Jr days...LOL

Congrats to Riida!
Another drama starring role!!!!
The costume is hilarious...! But extremely cute...
I cannot imagine too many 28 y.o. male who can pull that costume off!
Well...Ganbatte!

By for now.

P.S. I know I have been away ...but lurking in the background...did come out and posted fanvid for Riida's B'day but took it down after a few days due to personal decision (nothing bad) and did not have time to post any replacement...but now...I thought I better share the translations with you Riida lovers! Hope I helped some Riida fans desperate to get more details about the drama!

P.P.S. Sorry for not being able to respond to comments - they are appreciated...
BTW...I can only read and write in English and Japanese...LOL!

P.P.P.S. Having trouble with email account...trying to get it sorted.
