Q: please Help me with My story!

I've come up with an idea for a story, but I'm having a hard time coming up with a 'rest-of-the-story' type thingy...
so here's the beginning, a pretty but unfortunately unlucky girl (go figure), is walking to school one ngày and finds this Halloween-like looking box (with swirlies :3), she tries to open it but it won't open (yet!), but over the course of 5 days the swirls on each side of the box slowly but surely unravel until the box is completely blank, and at midnight the box opens and a nightmarish appearing creature arises in the moon light, the tiếp theo ngày the girl (still haven't figured out a name, yet!) spends the ngày with her friends, and comes trang chủ to a freighting 'thing' swoop past her and hides in her closest, (despite the fact of all the horror phim chiếu rạp that teach bạn NOT to open the door...) she opens the closet door, the nightmarish creature leaps at her, and turns out to be a Neko (a guy in fact, funny actually...) that was trapped in side the box, supposedly lucky, as thanks for releasing him would help her with her life's misfortunes.
(the picture(s) below are idea's of the appearence of the box and the neko, not original, from Pandora hearts, but the idea still counts!)
