I'm translating a Korean song into English.
<My heart can’t stop pounding even as we parted.
"We used to love each other."
It still seems like that now.
The pain doesn’t wash away.
Though I tried several times to endure it.
It’s so hard to live day by day without you.
You are my life.>
Which one sounds more poetic and fluid?
a) "We used to love each other. It still seems like that now."
b) "We once loved each other. It still seems like that now."
Also, feel free to suggest me better words/expressions.
