Wow did she get no inheritance from her parents?? At all??
Also nice landlord my ass, he kicked her out of her apartment the day of her parent's funeral and moved all her stuff to his house without asking! Also if you need someone to tidy up get a maid... don't just decide that some girl is gonna be your wife and give up everything just to keep the house clean... all adults should be able to take care of themselves!
I'm sorry but the suspension of disbelief required to enjoy this manga is almost too much! Maybe I'm just being a sour grape but... the clichès!
