My Mortal Enemy Always Wants to Have Sex with Me

I am the latest model of housekeeping android, sold to a family of three. The hostess bosses me around every day, and the male host occasionally looks at me strangely. Only their taciturn son would always sneak into the charging room late at night. He rubbed the serial number plate on the back of my neck over and over again, his voice trembling: "The seventh one shipped in 2017... Isn't it really you?" I executed the program settings and asked blankly: "What service do you need?" Until one day the system went crazy and I blurted out: "Xiao Ming, you have grown taller."
