Best Friend's Instruction Manual
Description
"Is this how you're supposed to do it?" "Don't just try to use force, shake it gently and well." "Wow, it really got bigger when I shook it!" "Do I have to keep rubbing it like this for the liquid to come out?" "Oh! It came out!!" "Hey! Aim properly! It's getting everywhere!" "Oh, sorry..." Kim Nam-joo, and I, Park Yeo-joo. We are business partners who run an advertising company together, and we are also old best friends. And to save our failing company, we will personally use adult products and write reviews.
