The title of the song i used in chapter 10 is " Only Then " it was covered by Jungkook of BTS.
Here's the translation.
The way to love me isn’t hard
Just hold me tight like you are now
We don’t know what will happen to us later
But I like that nothing’s decided
Who cares what others say?
We can’t live without each other, so what’s the problem?
We can be more in love together
If you start to like someone else
If I get used to not being with you
When that time comes, when it’s that time
Only then we can break up
The way to love you isn’t hard
If I smile once more and care for you more
The way we love isn’t hard
If we look at each other like it’s the first time every time
Who cares what others say?
We can’t live without each other, so what’s the problem?
We can be more in love together
If you start to like someone else
If I get used to not being with you
When that time comes, when it’s that time
Then, then
Whether you want it or not, I’m going to hold onto you
When I get too tired that I can’t even walk
When that time comes, when it’s that time
Only then we can break up
Only then we can break up
