Okay so let me all remind you that Suha's family has always been in debt with Jiwoons grandmother because she helped them since Suha's childhood. Suha always agree to whatever the old hag says and Jiwoon knows that. That's the very reason why Suha still care for that old hag. And i hope Jiwoons grandmother will not get in the way if Jiwoon tries to bring down the red head guy.
This is so fucked up.
