Kirei na Onee-san ni Yashinawaretakunai Otokonoko Nante iru no?

Life together with a beautiful, rich, slightly older and a bit mysterious young lady starts now!
"You won't ever have to work in life, you know"
The person who saved me when i lost my place to live and part time job, due to my father's disappearance, was a young lady who was a regular customer at my part time job. She gave me a room to live in until i was able to stand on my own feet, in exchange for me helping her with the house chores, since she's poor at doing them. After only tydying up, the reward she gave me was.... a stack of cash... just who is this lady?! "If it's money that you need, i can give you as much as you want so please become my full time househusband!"
Even though i'm only looking to live a regular life, how did it come to this...
