In which a girl can't go a day without an anxiety attack and a boy can't go a day without noticing

A remade story I'm making

He learns that even though he wasn't there for them while they were growing up, they respect him and love him as their father. Follow this strange family as they hunt down a Graboid nest and once again, rid the world of these monster worms and their kin.
