First heard this song in 2007
when NEWS made a redebut after their 1 year suspension

The first people I thought of when I heard this song
was my 7duohua <3
I always like to look for friendship songs
and dedicate them to different people in different stages of my life
sometimes I will dedicate the same song to a few group of people
but this song belongs to my 7duohua only =D

I mean this song totally just describes us
and you guys are the people who have watched me grow up (Just as I have watched you guys grow up)

So now I'll dedicate this song to you guys =D

くだらないことで 盛り上がり
気がつけば朝まで 笑いあった
大人になったはずなのに 何も変わってないね

Getting excited over useless stuff
and before we knew it, it's already morning
Even though we have become adults
nothing has changed

You are my Best Friend
照れくさいから ありがとうなんか言えない
特别な场所じゃないけど ずっとここにいたいんだ

You are my Best Friend
Because it's embarrassing, I can't say 'Thank You'
It's not a special place, but I always want to be here with you

僕らの育った町并みは
あの顷とは违う 姿になったね
めぐり来る季节越えても 君は変わらないで

The town that we grew up in
has changed since we were last there
Even as seasons come and go, you haven't changed at all

You are my Best Friend
ささいなことで たまにはケンカもするさ
ぶつけ合った気持ちの数だけ 分かり合える

You are my Best Friend
Sometimes we will quarrel over trivial things
But as we spend more time together, we will understand each other better

この先も 声に出すことはないと思うけど
本当は キミといる时が一番 心が温かいよ

Even though I have not voiced it out before
but I feel the most comfortable being with you

You are my Best Friend
照れくさいから ありがとうなんか言えない
特别な场所じゃないけど ここにいたいんだ

You are my Best Friend
Because it's embarrassing, I can't say 'Thank You'
It's not a special place, but I always want to be here with you

You are my Best Friend
どんな时だって 僕たちは一人じゃないさ
何気ない优しさをくれる 君だけに ありがとう

You are my Best Friend
We will never be alone
To you who have selflessly shown me your kindness, 'Thank You'

and ohoh
although I have dedicated this song to huangcheng peeps before (because it talks about staging a performance together)
but there's this one verse that's for you guys

(山)悲しい时だって笑って泣いて泣いて忘れよう
用事もないのに集まって
意味のない会话にただ笑ったね
例えば离れてたって心はひとつに繋がってるよ
いつも そばに I promise you

Translation
When you're sad, laugh and cry and then forget about it
Even if there's nothing important
Let's gather together and talk about things
Even if we're apart, our heart will always be linked as one
I will always be with you I promise you

<3 you guys

Let's grow old together!

<3 Yihui
