First of all.
Running away is highly risky for students. You better know where you should be going too. Best is some countryside far away from city. Just like for real, report her problems to police and then cry about it later.
You have money to worry about, you friends(most likely these two have no one), and the mc family gonna be worry and start questions about the girl he running with.
And from what I see, this girl rely on mc too much now. If the mc fall she break too.
I thought he fixed her but, he just made her more fragile.
Like many said. This ain't end well.
