Chapitre 1431: Don't destroy it

 REN

"For example 'A little pain.' The chorus 

Please realize 

I'm here waiting for you 

even if the future awaiting us is unlike today 

I'm here waiting for you 

and I keep on screaming 

I'm sure my heart is tugging on the string that binds us, 

so that the me back then will open her eyes 

Here you can see that she's talking about the future. She already knows that at the end of this she will have to go her separate ways with him even if she loves him." Ren explained.

But this also means that even if they separate. She will always wait for him. In that time Ren wonders if he will be able to fulfil the gap in her heart, if it's even possible to do so.
