He's your bestie since childhood. But at 16, he had to leave faraway because he registered himself as a singer & songwriter at an agency

Since that day, he lost contact with you for 5 years, because of the agency rule. But you NEVER knew that for the whole 5 years, he kept making songs about you. His memories, secret feelings & euphoria when he's with you back then

'When you smile, you always make me think about my future with you'

The lyrics says
