I'm a rental boyfriend in Dongying

He got a sand sculpture system called rental boyfriend, and asked him to be a rental boyfriend, and successively became the rental boyfriend of Yukinoshita Yoshino, Kaner Nayuta, and Xinggong Liukui.
That's right, I, Sixteen Nights, not only want to be their boyfriend, but also use their money to go on dates and charge on time.
There is a senior sister named Kong Yinzi.
I also have to take care of a middle-aged loli named Remilia who claims to be a five-hundred-year-old vampire.
When will you be able to relax on days like this?
