爱我的那个姐姐……

她睡在镜子的另一侧，

所以我要把她带回来，

我必须把她带回来……

【以防看不清镜子里面有啥放了两版】

又是被尤尼姐妹情深感动的一天呢【？】

The girl who loves me...

She is asleep on the other side of the mirror,

So I am going to bring her back,

I must bring her back...

【I set up two versions in case you can't make out what is inside of the mirror】

Another day I'm deeply moved my Uni sisters' love (?)
