In the earliest, 

We thought of excuses to talk 

Both of them waiting for a 'hi' to pop up

Shyness turned to comfort

When conversation continued from one day to another

'Bye' in the conversation was on a verge of extinction

Nights turned longest 

When they learned about each other more, at around 2 am

They were no longer strangers

But they didn't call themselves lovers 

They were lovers in making

Or 

Just nothing
