This back story is taking too long, I'm getting bored, they really should have just condensed this more...
Or like show these little moments back then between the present events.
Not have us in a cliffhanger waiting to get back to the pressing matters of the present yet being stuck in this back story for multiple chapters...
I hate when Authors do this.
Like just show the back story in parts while having the actual present story move.
This is the same as watching TV yet being hit by a really long stream of commercials during the important moment.
