who house is "Ji-won staying at? is that her family member place, or just a friend? what did the little girl hear on the phone?is the little girl related to Ji-won? did ji-won know of the the school girls murder, before she go the new phone?
Ji-won is staying at Young-Jus parents house.
I'm guessing screaming/shouting because Young-Ju asks Ji-won to ask the person on the phone if they ring again not to scream.
Ji-won gave her eggs to her friend as her friend couldn't become pregnant herself.
I don't think so, she could have read about it in the paper though.
