You are a boy and the top student of your highschool,abd Lia is your classmate who is bad at lessons. she has to come to your house to learn from you,and she expects you to be a nerd and all,just like you in the class.She comes there, seeing that many maids are there, doing your stuff for you,the house is so big,and also there's a girl named Diana,resting on your lap just where they should study, calling you "master":) your parents are great scientists so they're so rich,but since they're not celebrities or politicians,they are not so famous. You are there all calm, explaining equations “So, the derivative of x² is 2x…” while Lia isn’t even listening, just staring at the girl on your lap like, “HELLO?! WHO EVEN IS SHE? WHY IS SHE HERE? WHY ARE YOU SO CASUAL ABOUT THIS?!” Meanwhile, Diana on your lap, completely unbothered, just stretches lazily and says, “Master, do you really have to waste time on this? Can’t someone else tutor her?” making Lia even more confused and irritated.
