This song is about Jacob’s mother he mentions this in an interview with Nolala:

It is a common misconception that it is about ‘boy meets girl‘, but one of the biggest inspirations for the song is my mother.
She has been a nurse since she was 18 and has raised 4 children. My mother chose to run night shifts just so that she could spend time with us during the day. She’d start working at 8pm, came home around 8am and slept until noon, so when we came home, she’d be there for us. Fast forward to 32 years later. She is now 50 years old and having her knees replaced, that is the sacrifice she made for love. She chose to stay up every night because love is expensive. Not literally, but you have to give something.
