I did a quick translation of the song, please have in mind that it's very subjective hehe
Today is goodbye, my heart hurts
You'll write me letters won't you?
Seishun Bus Guide, you're radiant,
Now is a good time for a photo
It felt like a love at first sight, I bursted of excitement
It's an unstoppable feeling, it must be love right?
While you pass by us, you leave a nice smell
You're nice to everyone
I want to be by myself with that voice, that smile, that everything
Seeing you makes me numb, I want to be by myself
But, goodbye, my heart hurts
I want to talk more with you
Seishun Bus Guide, you're radiant
I wish to be reborn as a microphone
All these guys are my rivals,
while talking to them this feeling becomes stronger, it's jealousy
During the break I got to talk with you,
your eyelashes are so long
It's time to come back, I want to return on the first day
I want to tell you, it's time to come back
I want to be by myself with that voice, that smile, that everything
Seeing you makes me numb, I want to be by myself
Today is goodbye, my heart hurts
You'll write me letters won't you?
Seishun Bus Guide, you're radiant,
Now is a good time for a photo
But, goodbye, my heart hurts
I want to talk more with you
Seishun Bus Guide, you're radiant
I want to meet you once more

So.. it's a goodbye song. To the Bus Guide that all of these ikemen fell in love with
lol@the microphone part. Talk about otaku-like lyrics...
