I'll leave the door on the latch 
If you ever come back if you ever come back
There'll be a light in the hall and a key under the mat 
If you ever come back
There'll be a smile on my face and the kettle on 

And it will be just like you were never gone.

Sehun is stuck somewhere in time, hoping he'd come back.

All I remember was that we were just arguing for more than three months until he gave up. I never expected this. It's been a month, and I'm still waiting, Lu. Everything's the same ever since you left.

Come back.

I need you.

Do you hear it?

My heart, it's still beating for you. You were right.
