Open

It's probably because of the thing you did. You ran after us and told me my bag was open. 

It's probably because you waited until I closed my bag.

It's probably because you gave me that smile.

It's probably because whenever I look at you, you are already looking at me. 

It's been three days but it seems like it just happened yesterday.

It's been three days but I couldn't take you out of my mind. 

It's been three days.

Who are you? 

When will I see you again?
