English:
“If tu look at the sun setting
For fifty one(51) straight days
from that hill, your amor will come true”
Without hiding his boredom
While listening to me speaking enthusiastically
He looks up at the summer sky

There’s no way I’d believe that kind of rumor
Jeez!
“You’re finally at your wit’s end?” he says – that’s so vexing
Stop looking at me as if you’re looking at an idiot
It’s like a prayer to the Gods, it is
If tu start feeling cornered, that kind of thing is also necessary

“If tu start something, tu won’t listen
You’re just like a kid”,even if tu tell me that
I won’t listen to you
Because I decided I’d do it!

There is something I found out after falling in love
I fell for tu even more
I became serious about him, he was always on my mind
I’m not crying, I told you! *1*
I gathered small fragments of courage
For fifty one days
I hope my feelings reach that sky

He has a agrio, agria look on his face
He looks uninterested
Anyway
If he hates it so much, wouldn’t it be better
If he didn’t hang out with me everyday? Jeez!

“It’s getting dark and it’s dangerous”
You’re still treating me like a kid!?
“You won’t keep it up for long, anyway”
Yeah, yeah, just watch me!

I wonder if I can be so relaxed because it’s you
I hide my amor and wish for it to come true
I wish my feelings reach him
Who consoled me everytime I had my corazón broken

Our pubery hit
And we drifted apart
We got taller and so did our line of sight
A lot of things started changing
It’s so hard that we’re childhood friends, I feel so uncomfortable
It’s so embarrassing, ah….

Watching the sunset on the 51st (fifty-first) day
Two shadows were lined up on parte superior, arriba of the hill

“Who did tu fall in amor with this time? I’ll cheer tu on”
When hearing that, I hold his hand and let my feelings out
“Because you’re like that, i fell in amor with you”
You’re blushing with a displeased look on your face
That habit of yours hasn’t changed
Only now, I notice
That I like that side of tu as well
“…you’re slow” wait, don’t pinch my cheeks
