These lyrics, translated from Korean, have a somewhat different style and emphasis than American love songs. I've edited parts out to condense:
Boy My First Love StoryI don't think Americans songs are so openly shy and embarrassed.
You're so so handsome
My eyes my eyes are blinded
I can't breathe because I'm trembling
Oh I feel so embarrassed
I can't look at you
I feel shy because I've fallen in love
What should I do? (What should I do~) About my trembling heart (My trembling heart)
(Thump thump thump thump) My heart kept thumping
So I couldn't fall asleep at night
My close friends tell me
That I'm really a helpless fool
But as I look at you~~
So tingly tingly my body is trembling gee gee gee gee gee
Oh your glittering eyes (oh yeah~) Oh this sweet aroma (oh yeah yeah yeah~)
I can't even say anything
I'm too embarrassed
Do I not have any courage?
What would be the right thing to do?
Thump thump my heart is anxious as I'm looking at you
In any case, how can you be in love with someone you're "too embarrassed" to "say anything" to? In other words, how can you be in love with someone whom you do not have a relationship with at this time?
It's in the beginning of the song: the boy was handsome. He had a desirable characteristic that made him a good potential mate.
