The one that got away

This story is based around the song The One That Got Away, except they're still in high school. Also I'm not shipping them in real life, just their characters. Also their personallities might nit match to actual them, I had to change it to fit the story.

Sapnap never had the best parents to say... His parent had basically been neglecting him since the age of 10, which was 7 years ago. Their excuse was that he was old enough to take care of himself. Sapnap has his lisencens but doesn't own a car.

Karl is a thoughtful and caring boy who always strived to help. His father left him when he was 3 and his mother drank a lot. She still took care and helped him but she wasn't always emotionally there for him. When he moves to his new neighbor hood, he has trouble finding friends and decides that the local Sub-today is the best place to take a breather.

What happens when these two meet and eventually 𝒇𝒂𝒍𝒍 for each other?
