My brother and sister, whose parents died in an accident, were taken in by a distant relative's house. Actually, I have to do something to protect my sister Yui, but I can't afford to pay the rent, let alone the tuition fee. I just couldn't help but be ashamed of myself. After graduating from college and getting a job, I will try to make Yui happy without anyone else's help. Until then, I decided to take care of the Koizumi family.
