TRANSLATION

Our eyes lock and we smile at each other
My heart is racing feels like I'm going crazy
Just like bubbles bursting our love is beautiful
Will you kiss me with your sweet lips

On my way back from taking you home
I remember our kiss and I stop in place
I call you on the phone and ask if you could come out again
I miss you so much I'm sorry for saying nonsense this late at night

Our date a love date
When we do it once I want to do it again
Today is a beautiful day
Let's share love every night
Day or night without anyone knowing
Today is a beautiful day

Hey my sweet you're so sweet
I can't quit you I love it when you're in my arms
I get surprised by seei
