fantasy_land good novel so far.
early few chapters are really short, you should consider re-writing them.
try to plan chapters in advance, so you can merge them if they are short.
also, emotions needs more description.
develop side characters, i still on't know her grandpa's or his father's name.
it should be sister rather than short sis before they met, can't be that casual before meeting.(sis-in-law or bro-in-low)
more quantity require because people will find mistakes or loop hole in writing, if it's short.(like,how his grandpa barged in her office, without prior notice from her secretary. you need to clear up things like that.)
